LBuffer::SetHandle

#include "ltwrappr.h"

L_INT LBuffer::SetHandle(pMemHandle, dwSize=0)

HGLOBAL * pMemHandle;	/* pointer to a global memory handle */
L_SIZE_T dwSize;	/* size of the global handle */

Initializes the class object with an allocated global buffer handle.

Parameter	Description
pMemHandle	Pointer to a global memory handle.
dwSize	The size of the global memory handle. Pass 0 to let the function get the size.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

You can use this function to have the class object manipulate a buffer that you have previously allocated. This memory will be automatically freed when the class object is destroyed.

If the object already has an allocated buffer associated with it, that buffer is freed before the new handle is set.

The passed memory handle will be invalidated after this operation.
