#include "ltmm.h"

C Syntax	HRESULT IltmmMemory_SetData(pMem, Index, Count, Data)
C++ Syntax	HRESULT SetData(Index, Count, Data)

IltmmMemory *pMem;	/* pointer to an interface */
long Index;	/* offset */
long Count;	/* size */
VARIANT Data;	/* data to set */

Sets new data in the objects buffer, at the specified index, with the specified size.

Parameter	Description
pMem	Pointer to an IltmmMemory interface.
Index	Index (offset) at which to set the new data in the objects buffer.
Count	Size, in bytes (number of byte elements), of the data to set.
Data	VARIANT containing a reference to a SAFEARRAY of data. The array should have one dimension and should contain byte elements.

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

If the size of the data to set is larger than the size available after the offset, the function will update only the available space between the offset and the end of the buffer.

The area of the buffer to which the new data is copied will be locked for the duration of the call.
