Member Function Documentation

Instance()

SysInfo & ts::SysInfo::Instance ( )

static

Get the instance of the singleton of this class.

Returns

The instance of the singleton of this class.

arch()

SysArch ts::SysInfo::arch ( ) const

inline

Get the architecture of the CPU on which we run. This can be different from the preprocessing directives. For instance, on Windows, the actual CPU can be INTEL64 but the compiled code can be INTEL32.

Returns

The architecture of the CPU on which we run.

os()

SysOS ts::SysInfo::os ( ) const

inline

Get the operating system family.

Returns

The operating system family.

osFlavor()

SysFlavor ts::SysInfo::osFlavor ( ) const

inline

Get the operating system flavor.

Returns

The operating system flavor.

crcInstructions()

bool ts::SysInfo::crcInstructions ( ) const

inline

Check if the CPU supports accelerated instructions for CRC32 computation.

Returns

True if the CPU supports CRC32 instructions.

systemVersion()

UString ts::SysInfo::systemVersion ( ) const

inline

Get the operating system version.

Returns

The operating system version.

systemMajorVersion()

int ts::SysInfo::systemMajorVersion ( ) const

inline

Get the operating system major version as an integer. The exact meaning of this number is system dependent.

Returns

The operating system major version or -1 if unknown.

systemBuild()

int ts::SysInfo::systemBuild ( ) const

inline

Get the operating system build as an integer. The exact meaning of this number is system dependent. On Windows, it returns the Windows build number.

Returns

The operating system build or -1 if unknown.

systemName()

UString ts::SysInfo::systemName ( ) const

inline

Get the operating system name.

Returns

The operating system name.

hostName()

UString ts::SysInfo::hostName ( ) const

inline

Get the name of the system host.

Returns

The name of the system host.

cpuName()

UString ts::SysInfo::cpuName ( ) const

inline

Get the name of the CPU architecure.

Returns

The name of the CPU architecure.

cpuCoreCount()

size_t ts::SysInfo::cpuCoreCount ( ) const

inline

Get the number of CPU cores. This is typically the number of logical cores, which can be different from the number of physical cores when they implement some form of hyperthreading. The result can be the same as std::thread::hardware_concurrency() but the latter is documented to be considered as a hint only and not accurate.

Returns

The number of CPU cores.

memoryPageSize()

size_t ts::SysInfo::memoryPageSize ( ) const

inline

Get system memory page size.

Returns

The system memory page size in bytes.

GetSystemVersion()

ts::UString ts::SysInfo::GetSystemVersion ( )

static

Build a string representing the system on which the application runs.

Returns

A string describing the system.

GetCompilerVersion()

ts::UString ts::SysInfo::GetCompilerVersion ( )

static

Build a string representing the compiler which was used to build TSDuck.

Returns

A string describing the compiler.

GetAccelerations()

ts::UString ts::SysInfo::GetAccelerations ( )

static

Build a string describing the hardware accelerations on the system on which the application runs.

Returns

A string describing the hardware accelerations.
