IltmmMemory::get_BufferSize

#include "ltmm.h"

C Syntax	HRESULT IltmmMemory__get_BufferSize(pMem, pVal)
C++ Syntax	HRESULT get_BufferSize(pVal)

IltmmMemory *pMem;	/* pointer to an interface */
long *pVal;	/* pointer to a variable */

Retrieves the size of the memory object’s buffer, in bytes.

Parameter	Description
pMem	Pointer to an IltmmMemory interface.
pVal	Pointer to a variable to be updated with the size of the object’s buffer, in bytes.

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

This gets the size set using IltmmMemory::put_BufferSize. If you call this before calling IltmmMemory::put_BufferSize, this function updates the variable pointed to by pVal with 0.
