Poll.wait

int wait(gst.types.ClockTime timeout)

Wait for activity on the file descriptors in set. This function waits up to the specified timeout. A timeout of #GST_CLOCK_TIME_NONE waits forever.

For #GstPoll objects created with [gst.poll.Poll.new_], this function can only be called from a single thread at a time. If called from multiple threads, -1 will be returned with errno set to EPERM.

This is not true for timer #GstPoll objects created with [gst.poll.Poll.newTimer], where it is allowed to have multiple threads waiting simultaneously.

Parameters

timeouta timeout in nanoseconds.

Returns

The number of #GstPollFD in set that have activity or 0 when no

activity was detected after timeout. If an error occurs, -1 is returned and errno is set.
