GetAndWait()

Get a buffer of media data, waiting until a buffer is available or for a fixed time period

Synopsis:

#include <OMXAL/OpenMAXAL_QNX.h>

struct XAQNXVideoBufferQueueSourceItf_ {
    XAQNXBuffer* (*GetAndWait)(XAQNXBufferQueueSinkItf self,
                               const struct timespec *abstime);
} ;

Arguments:

self: A reference to the sink interface
abstime: A pointer to an immutable timespec structure specifying the waiting period

Library:

mmfilter

Description:

This function attempts to get a buffer of media data. The function is blocking and waits for the amount of time given in abstime. This parameter can be NULL to wait indefinitely for a buffer to become available.

Returns:

A pointer to an XAQNXBuffer containing media data sent to the sink. If no data items were available (e.g., if playback or recording is stopped or the timeout expired), NULL is returned.
