HGLOBAL hMem,
SIZE_T dwBytes,
UINT uFlags
);

DECLARE INTEGER GlobalReAlloc IN kernel32;
INTEGER hMem,;
LONG dwBytes,;
LONG uFlags
|
|
|
|
| Parameters: |
|
hMem
[in] A handle to the global memory object to be reallocated. This handle is returned by either the GlobalAlloc or GlobalReAlloc function.
dwBytes
[in] The new size of the memory block, in bytes. If uFlags specifies GMEM_MODIFY, this parameter is ignored.
uFlags
[in] The reallocation options. |

| If the function succeeds, the return value is a handle to the reallocated memory object, otherwise it is NULL. |

| My comment: |
|
If GlobalReAlloc reallocates a movable object, the return value is a handle to the memory object. To convert the handle to a pointer, use the GlobalLock function.
If GlobalReAlloc reallocates a fixed object, the value of the handle returned is the address of the first byte of the memory block. To access the memory, a process can simply cast the return value to a pointer.
