#include "ltmm.h"

C Syntax	HRESULT IltmmMediaSampleDisp_get_SyncPoint(pMediaSampleDisp, pVal)
C++ Syntax	HRESULT get_SyncPoint(pVal)

IltmmMediaSampleDisp *pMediaSampleDisp;	/* pointer to an interface */
VARIANT_BOOL *pVal;	/* pointer to a variable */

Determines if the beginning of this sample is a synchronization point.

Parameter	Description
pMediaSampleDisp	Pointer to an IltmmMediaSampleDisp interface.
pVal	Pointer to a variable to be updated with a value that indicates whether the beginning of the sample is a synchronization point. Possible values are:
	Value	Meaning
	VARIANT_TRUE	The beginning of the sample is a synchronization point.
	VARIANT_FALSE	The beginning of the sample is not a synchronization point.

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.
