The MAPIAllocateBuffer function allocates a memory buffer.

Syntax

SCODE MAPIAllocateBuffer(
  ULONG cbSize, 
  LPVOID FAR* lppBuffer 
);

Parameters

  • cbSize
    [in] Size, in bytes, of the buffer to be allocated.
  • lppBuffer
    [out] Pointer to the returned allocated buffer.

Return Value

  • S_OK
    The call succeeded and has returned the expected value or values.

Remarks

During MAPIAllocateBuffer call processing, the calling implementation acquires a block of memory from the operating system. The memory buffer is allocated on an even-numbered byte address. On platforms where long integer access is more efficient, the operating system allocates the buffer on an address whose size in bytes is a multiple of four.

Calling the MAPIFreeBuffer function releases the memory buffer allocated by MAPIAllocateBuffer and also releases any additional buffers that have been linked to it through the MAPIAllocateMore function.
