DWORD HeapSize(
HANDLE hHeap, // handle to heap
DWORD dwFlags, // heap size options
LPCVOID lpMem // pointer to memory
);
|
|
|
|
| FoxPro declaration: |
|
|
DECLARE INTEGER HeapSize IN kernel32;
INTEGER hHeap,;
INTEGER dwFlags,;
INTEGER lpMem
|
|
|
|
| Parameters: |
|
hHeap
[in] Specifies the heap in which the memory block resides. This handle is returned by the HeapCreate or GetProcessHeap function.
dwFlags
[in] Specifies several controllable aspects of accessing the memory block.
lpMem
[in] Pointer to the memory block whose size the function will obtain. This is a pointer returned by the HeapAlloc or HeapReAlloc function. |
|
|
| Return value: |
