IltmmMultiStreamTarget::WaitForSample

#include "ltmm.h"

C Syntax	HRESULT IltmmMultiStreamTarget_WaitForSample(pMultiStreamTarget, lTimeout, Stream);
C++ Syntax	HRESULT WaitForSample(lTimeout, Stream);

IltmmMultiStreamTarget *pMultiStreamTarget;	pointer to an interface
long lTimeout;	time interval
long * Stream;	pointer to a variable

Wait for a sample from any source to get ready.

Parameter	Description
pMultiStreamTarget	Pointer to an IltmmMultiStreamTarget interface.
lTimeout	Time-out interval, in milliseconds. The time the function will wait for a sample to be ready. If the time elapses and no sample is ready, the function will return a time-out error code. If lTimeOut is -1, the function's time-out interval never elapses.
Stream	Pointer to a variable that will receive the stream number for which the sample is indicated as ready. A stream value of 1 indicates an invalid stream.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

The function must be called in the running state; calling it in the stopped state or after the end of stream is reached will return a wrong state code.
