GlobalHandle function
Retrieves the handle associated with the specified pointer to a global memory block.
Syntax
HGLOBAL WINAPI GlobalHandle( _In_ LPCVOID pMem );
Parameters
- pMem [in]
-
A pointer to the first byte of the global memory block. This pointer is returned by the GlobalLock function.
Return value
If the function succeeds, the return value is a handle to the specified global memory object.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
Remarks
When the GlobalAlloc function allocates a memory object with GMEM_MOVEABLE, it returns a handle to the object. The GlobalLock function converts this handle into a pointer to the memory block, and GlobalHandle converts the pointer back into a handle.
