IMallocSpy::PostGetSize
Called just after invoking
IMalloc::GetSize.
ULONG PostGetSize(
ULONG cbActual,
| //Actual size of the allocation
|
BOOL fSpyed
| //Indicates whether the allocation was done while a spy was active
|
);
|
|
Parameters
cbActual
The actual number of bytes in the allocation, as returned by
IMalloc::GetSize.
fSpyed
TRUE if the allocation was done while a spy was active.
Return Values
The size of the allocated memory block in bytes, which is returned to the
caller of
IMalloc::GetSize.
Comments
The size determined by
IMalloc::GetSize is the value returned by the Win32 API
HeapSize. On Windows NT, this is the size originally requested. On Windows95, 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 Windows95, the same request would return an allocation of
28 bytes and
GetSize would return 28. Implementors 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.
