The index of cmd in buffer or count() if not found.

◆ getByCommand()

uint32_t ts::DTVProperties::getByCommand ( uint32_t  cmd) const

Get the value of a property in the buffer.

Parameters
[in]cmdCommand code.
Returns
The data value of cmd in buffer or UNKNOWN if not found.

◆ getByIndex()

uint32_t ts::DTVProperties::getByIndex ( size_t  index) const
inline
