.. _AUDIO_GET_PTS:
=============
AUDIO_GET_PTS
=============
Name
----
AUDIO_GET_PTS
Synopsis
--------
.. c:function:: int ioctl(int fd, int request = AUDIO_GET_PTS, __u64 *pts)
Arguments
---------
.. flat-table::
:header-rows: 0
:stub-columns: 0
- .. row 1
- int fd
- File descriptor returned by a previous call to open().
- .. row 2
- int request
- Equals AUDIO_GET_PTS for this command.
- .. row 3
- __u64 \*pts
- Returns the 33-bit timestamp as defined in ITU T-REC-H.222.0 /
ISO/IEC 13818-1.
The PTS should belong to the currently played frame if possible,
but may also be a value close to it like the PTS of the last
decoded frame or the last PTS extracted by the PES parser.
Description
-----------
This ioctl is obsolete. Do not use in new drivers. If you need this
functionality, then please contact the linux-media mailing list
(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__).
This ioctl call asks the Audio Device to return the current PTS
timestamp.
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 <gen-errors>` chapter.
