1/6/2010

This method returns the size (in bytes) of a memory block previously allocated with the IMalloc::Alloc or IMalloc::Realloc method.

Syntax

ULONG GetSize(
  void* pv 
);

Parameters

  • pv
    [in] Pointer to the memory block for which the size is requested.

Return Value

The size of the allocated memory block in bytes or, if pv is a NULL pointer, -1.

Remarks

To get the size in bytes of a memory block, the block must have been previously allocated with IMalloc::Alloc or IMalloc::Realloc. The size returned is the actual size of the allocation, which may be greater than the size requested when the allocation was made.

To determine whether the platform supports this interface, see Determining Supported COM APIs.

Requirements

Header objidl.h, objidl.idl
Library ole32.lib
Windows Embedded CE Windows CE 3.0 and later
