Synopsis
--------
.. c:macro:: DMX_GET_PES_PIDS
``int ioctl(fd, DMX_GET_PES_PIDS, __u16 pids[5])``
Arguments
---------
``fd``
File descriptor returned by :c:func:`open()`.
``pids``
Array used to store 5 Program IDs.
Description
-----------
This ioctl allows to query a DVB device to return the first PID used
by audio, video, textext, subtitle and PCR programs on a given service.
They're stored as:
======================= ======== =======================================
PID element position content
======================= ======== =======================================
pids[DMX_PES_AUDIO] 0 first audio PID
pids[DMX_PES_VIDEO] 1 first video PID
pids[DMX_PES_TELETEXT] 2 first teletext PID
pids[DMX_PES_SUBTITLE] 3 first subtitle PID
pids[DMX_PES_PCR] 4 first Program Clock Reference PID
======================= ======== =======================================
.. note::
A value equal to 0xffff means that the PID was not filled by the
Kernel.
Return Value
------------
On success 0 is returned.
On error -1 is returned, and the ``errno`` variable is set
appropriately.
The generic error codes are described at the
:ref:`Generic Error Codes <gen-errors>` chapter.
