IMallocSpy::PostGetSize
Called just
after invoking IMalloc::GetSize.
ULONG PostGetSize(
|
ULONG cbActual, |
//Actual size of the allocation |
|
BOOL fSpyed |
//Whether the allocation was done while a spy was
active |
|
); |
|
Parameters
cbActual
[in] Actual
number of bytes in the allocation, as returned by IMalloc::GetSize.
fSpyed
[in] TRUE if
the allocation was done while a spy was active.
Return Values
The same
value returned by IMalloc::GetSize, which is the size of the allocated memory
block in bytes.
Remarks
The size
determined by IMalloc::GetSize is the value returned by the Win32
function HeapSize. On Windows NT, this is the size originally requested.
On Windows 95, memory allocations are done on eight-byte boundaries. For
example, a memory allocation request of 27 bytes on Windows NT would return an
allocation of 32 bytes and GetSize would return 27. On Windows 95, the
same request would return an allocation of 28 bytes and GetSize would
return 28. Implementers of IMallocSpy::PostGetSize cannot assume, for
example, that if cbActual is sizeof(debug_header), that the value is the
actual size of the user s allocation.
