GlobalHandle function (winbase.h)

Article
02/22/2024

Retrieves the handle associated with the specified pointer to a global memory block.

Note The global functions have greater overhead and provide fewer features than other memory management functions. New applications should use the heap functions unless documentation states that a global function should be used. For more information, see Global and Local Functions.

Syntax

HGLOBAL GlobalHandle(
  [in] LPCVOID pMem
);

Parameters

[in] pMem

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.
