If no audio stream type is +set the id has to be in [0xC0,0xDF] for MPEG sound, in [0x80,0x87] for +AC3 and in [0xA0,0xA7] for LPCM. More specifications may follow for +other stream types. If the stream type is set the id just specifies the +substream id of the audio stream and only the first 5 bits are +recognized. + +Return Value +------------ + +On success 0 is returned, on error -1 and the ``errno`` variable is set +appropriately. The generic error codes are described at the +:ref:`Generic Error Codes ` chapter. -- cgit v1.2.3
