Member Function Documentation

◆ open()

virtual bool ts::Socket::open ( IP gen = IP::Any )

finalvirtual

Open the socket.

Subclasses are not permitted to override this one, they should implement openImplementation().

Parameters

[in] gen IP generation, IPv4 or IPv6. If set to IP::Any, open an IPv6 socket (IPv4 connections allowed).

Returns: True on success, false on error.

◆ close()

virtual bool ts::Socket::close ( bool silent = false )

finalvirtual

Close the socket.

Subclasses are not permitted to override this one, they should implement closeImplementation().

Parameters

[in] silent If true, do not report errors through the logger. This is typically useful when the socket is in some error condition and closing it is necessary although it may generate additional meaningless errors.

Returns: True on success, false on error.

◆ isOpen()

bool ts::Socket::isOpen ( ) const

inline

Check if socket is open.

Returns: True if socket is open.

◆ generation()

IP ts::Socket::generation ( ) const

inline

Get the IP generation with which the socket was open.

Returns: The IP generation used to open the socket. Never IP::Any.

◆ setSendBufferSize()

bool ts::Socket::setSendBufferSize ( size_t size )

Set the send buffer size.

Parameters

[in] size Send buffer size in bytes.

Returns: True on success, false on error.

◆ setReceiveBufferSize()

bool ts::Socket::setReceiveBufferSize ( size_t size )

Set the receive buffer size.

Parameters

[in] size Receive buffer size in bytes.

Returns: True on success, false on error.

◆ setReceiveTimeout()

bool ts::Socket::setReceiveTimeout ( cn::milliseconds timeout )

Set the receive timeout.

Parameters

[in] timeout Receive timeout in milliseconds. If negative or zero, receive timeout is not used, reception waits forever.

Returns: True on success, false on error.

◆ reusePort()

bool ts::Socket::reusePort ( bool reuse_port )

Set the "reuse port" option.

Parameters

[in] reuse_port If true, the socket is allowed to reuse a local UDP port which is already bound.

Returns: True on success, false on error.

◆ bind()

bool ts::Socket::bind ( const IPSocketAddress & addr )

Bind to a local address and port.

The IP address part of the socket address must one of:

IPAddress::AnyAddress4.
- UDP: Any local interface may be used to send or receive UDP datagrams. For each outgoing packet, the actual interface is selected by the kernel based on the routing rules. Incoming UDP packets for the selected port will be accepted from any local interface.
- TCP client: Any local interface may be used to connect to a server.
- TCP server: Any local interface may be used to receive incoming client connections.
The IP address of an interface of the local system.
- UDP: Outgoing packets will be unconditionally sent through this interface. Incoming UDP packets for the selected port will be accepted only when they arrive through the selected interface.
- TCP client: Outgoing connections will be only allowed through this interface.
- TCP server: Incoming client connections will be accepted only when they arrive through the selected interface.

Special note for receiving multicast on most Unix systems (at least Linux and macOS): The IP address shall be either AnyAddress4 or the multicast group address. Do not specify a local address to receive multicast on Unix.

The port number part of the socket address must be one of:

IPSocketAddress::AnyPort. The socket is bound to an arbitrary unused local UDP or TCP port. This is the usual configuration for a TCP client.
A specific port number. If this UDP or TCP port is already bound by another local socket of the same type, the bind operation fails, unless the "reuse port" option has already been set.

Parameters

[in] addr Local socket address to bind to.

Returns: True on success, false on error.

◆ getLocalAddress()

bool ts::Socket::getLocalAddress ( IPSocketAddress & addr ) const

Get local socket address.

Parameters

[out] addr Local socket address of the connection.

Returns: True on success, false on error.

Returns: A string representation of the IP address and port of the socket.

◆ getReadHandle()

virtual SysHandleType ts::Socket::getReadHandle ( ) const

overridevirtual

inlinestaticinherited

This static method checks if a system error code means "I/O in progress" (asynchronous I/O) or "I/O would block" (non-blocking I/O).

Parameters

[in] error_code System error code.

Returns: True if error_code is an in-progress/would-block one.

◆ getHandle()

SysHandleType ts::NonBlockingDevice::getHandle ( ) const

inherited

Get the underlying file descriptor or device handle.

This method is reserved for low-level operations and should not be used by normal applications.

On UNIX systems, sockets are standard file descriptors. On Windows systems, sockets and devices handles are two distinct types (SOCKET, an integer type, and HANDLE, a pointer type). However, SOCKET and HANDLE have the same size and can be converted between each other. In practice, all Windows device handles are pointers. When Microsoft decided to implement the BSD socket API, they needed to represent sockets as integers. The integer is simply a cast of the HANDLE pointer.

In practice, the methods getHandle() and getSocket() return the same value, represented as two different portable types, SysHandleType and SysSocketType. Note that this types are defined as their real representation. On UNIX systems, both are defined as int and are compatible. However, on Windows systems, they are defined as HANDLE and SOCKET and are not compatible. So, accidentally mixing the two compiles on UNIX but not on Windows. Be careful to use the right type for the right usage.

There is one important difference between getHandle() and getSocket(): the error values, SYS_HANDLE_INVALID and SYS_SOCKET_INVALID. Be careful, these constants have distinct binary values on Windows. This is the only case were it is not possible to cast between a SysHandleType value and a SysSocketType value. This is why it is recommended to always use getHandle() when a SysHandleType is required and getSocket() when a SysSocketType is required.

A subclass which uses file descriptors or device handles for read, write, or both, must override the methods getReadHandle(), getWriteHandle(), or both. If the two types of operations use the same file descriptor, the two methods must return the same value.

An application should call getReadHandle() for read operations and getWriteHandle() for write operations. The method getHandle() returns getReadHandle() if its returns a valid value, and getWriteHandle() otherwise.

Returns: The underlying file descriptor or device handler. Return SYS_HANDLE_INVALID if the socket is not open.

◆ getSocket()

SysSocketType ts::NonBlockingDevice::getSocket ( ) const

inherited

Get the underlying file descriptor or device handle as a system socket handle.

Returns: The underlying socket descriptor. Return SYS_SOCKET_INVALID if the socket is not open.

See also: getHandle()

◆ getReadSocket()

SysSocketType ts::NonBlockingDevice::getReadSocket ( ) const

inherited

Get the underlying file descriptor or device handle as a system socket handle for read operations.

Returns: The underlying file descriptor for read operations or SYS_SOCKET_INVALID if the socket is not open for read.

See also: getHandle()

◆ getWriteSocket()

SysSocketType ts::NonBlockingDevice::getWriteSocket ( ) const

inherited

Get the underlying file descriptor or device handle as a system socket handle for write operations.

Returns: The underlying file descriptor for read operations or SYS_SOCKET_INVALID if the socket is not open for write.

See also: getHandle()

◆ checkNonBlocking() [1/2]

bool ts::NonBlockingDevice::checkNonBlocking	(	bool	non_blocking,
		const UChar *	opname
	)

protectedinherited

Check the blocking mode of a device.

Called by subclass methods which are explicitly called in blocking or non-blocking mode.

Parameters

[in]	non_blocking	The required non-blocking mode.
[in]	opname	Name of the operation, for the error message.

Returns: True on success, false on error.

◆ checkNonBlocking() [2/2]

bool ts::NonBlockingDevice::checkNonBlocking	(	IOSB *	iosb,
		const UChar *	opname
	)

protectedinherited

Check the blocking mode of a device.

Called by subclass methods which are explicitly called in blocking or non-blocking mode.

Parameters

[in,out]	iosb	Address of an IOSB structure. If non-null, we are in non-blocking mode. When null, we are in blocking mode. When non-null, pending is reset to false and overlap is zeroed.
[in]	opname	Name of the operation, for the error message.

Returns: True on success, false on error.

◆ setSystemNonBlocking()

bool ts::NonBlockingDevice::setSystemNonBlocking ( bool non_blocking )

protectedinherited

Low-level method to set the system file or socket descriptor in non-blocking mode.

Parameters

[in] non_blocking It true, the device is set in non-blocking mode.

Returns: True on success, false on error.

Summary: Do not use this method unless you exactly know what you are doing.

UNIX: Depending on the way a file descriptor is created, it may be possible to specify the non-blocking mode from the beginning. Or it can be somehow inherited. However, this is not portable.

Examples:

On Linux and FreeBSD, a socket can be directly created in non-blocking mode using the flag SOCK_NONBLOCK in the 'type' parameter of the socket() system call. However, it does not work on macOS.
On macOS (and maybe FreeBSD), when a server socket is in non-blocking mode, all client session sockets which are created by accept() are also in non-blocking mode. However, on Linux, they are in blocking mode.

In all cases, it is possible to set a file descriptor in non-blocking mode at any time using the method setSystemNonBlocking(). This method uses fcntl(F_SETFL) to alter the file descriptor's flags.

Windows: The natural way of not being blocked on I/O on Windows is asynchronous I/O. To increase the general confusion, there is some form of non-blocking mode on Windows sockets, and only sockets, not other forms of file handles. This mode is activated using "ioctlsocket(fd, FIONBIO, &mode)". When this mode is active, socket I/O become similar to UNIX: they immediately either succeed or fail, but never block. However, there is no way to get notified when the I/O becomes possible. There is no equivalent to epoll (Linux) or kqueue (macOS and BSD). The Windows I/O Completion Ports can only work on asynchronous I/O, using OVERLAPPED structures. Because this form of non-blocking mode is mostly useless in practice, we do not use it and the method setSystemNonBlocking() does nothing on Windows.

◆ genericSystemWrite()

int ts::NonBlockingDevice::genericSystemWrite	(	const void *	addr,
		size_t	size,
		size_t &	written_size,
		NonBlockingDevice::IOSB *	iosb,
		uint64_t	position
	)

protectedinherited

Generic system write operation.

This is a convenience method which can be used (or not) by subclasses when the system calls write() (UNIX) or WriteFile() (Windows) are appropriate.

Parameters

[in]	addr	Address of the data to write.
[in]	size	Size in bytes of the data to write.
[out]	written_size	Actually written size in bytes. Can be less than size in case of error in the middle of the write.
[in,out]	iosb	Address of an IOSB structure. If non-null, the stream must be in non-blocking mode. When null, the stream must be in blocking mode (the default). See the description of ts::NonBlockingDevice::IOSB.
[in]	position	This value is only used on Windows with asynchronous I/O on disk file. On Windows, when asynchronous I/O are used on random access files, the file position is not maintained. Each read or write operation is performed at the specified absolute position.

Returns: Error code. When the I/O is non-blocking/asynchronous and pending, return SYS_SUCCESS and iosb->pending is true. Return SYS_EOF when it is no longer possible to write (e.g. broken pipe).

◆ genericSystemRead()

int ts::NonBlockingDevice::genericSystemRead	(	void *	addr,
		size_t	max_size,
		size_t &	ret_size,
		const AbortInterface *	abort,
		NonBlockingDevice::IOSB *	iosb,
		uint64_t	position
	)

protectedinherited

Generic system read operation.

This is a convenience method which can be used (or not) by subclasses when the system calls read() (UNIX) or ReadFile() (Windows) are appropriate.

Parameters

[out]	addr	Address of the buffer for the incoming data.
[in]	max_size	Maximum size in bytes of the buffer.
[out]	ret_size	Returned input size in bytes. If zero, end of file has been reached or an error occurred.
[in]	abort	If non-zero, invoked when I/O is interrupted (in case of user-interrupt, return, otherwise retry).
[in,out]	iosb	Address of an IOSB structure. If non-null, the stream must be in non-blocking mode. When null, the stream must be in blocking mode (the default). See the description of ts::NonBlockingDevice::IOSB.
[in]	position	This value is only used on Windows with asynchronous I/O on disk file. On Windows, when asynchronous I/O are used on random access files, the file position is not maintained. Each read or write operation is performed at the specified absolute position.

Returns: Error code. When the I/O is non-blocking/asynchronous and pending, return SYS_SUCCESS and iosb->pending is true. Return SYS_EOF when it is no longer possible to read.

Report * ts::ReporterBase::setReport ( Report * report )

inherited

Associate this object with another Report to log errors.

Parameters

[in] report Where to report errors. The report object must remain valid as long as this object exists or setReport() is used with another Report object. If report is null, log messages are discarded.

Returns: The address of the previous Report object or a null pointer if there was none.

inherited

Temporarily mute the associated report.

Parameters

[in] mute It true, report() will return a null report (log messages are discarded), until muteReport() is invoked again with mute set to false.

Returns: Previous state of the mute field.

◆ SilentLevel()

static int ts::ReporterBase::SilentLevel	(	bool	silent,
		int	default_severity = `Severity::Error`
	)

inlinestaticinherited

Compute a log severity level from a "silent" parameter.

Some subclass methods have a "silent" parameter to avoid reporting errors which may be insignificant, typically when closing a device after an error, in which case the close operation may produce other errors if the previous error left the device in an inconsistent state. While those errors should not be displayed as errors, we still display them at debug level.

Parameters

[in]	silent	If true, do not report errors, report debug messages instead.
[in]	default_severity	Default severity, in non-silent mode (error by default).

Returns: Error when silent is false, Debug otherwise.
