Heap32First
Retrieves
information about the first block of a heap that has been allocated by a
process.
BOOL WINAPI Heap32First(LPHEAPENTRY32 lphe, DWORD
th32ProcessID,
DWORD th32HeapID);
Parameters
lphe
Address
of a buffer containing a HEAPENTRY32 structure.
th32ProcessID
Identifier
of the process context that owns the heap.
th32HeapID
Identifier
of the heap to enumerate.
Return Value
Returns TRUE
if information for the first heap block has been copied to the buffer or FALSE
otherwise. The ERROR_NO_MORE_FILES error value is returned by the GetLastError function if the heap is
invalid or empty.
Remarks
The
calling application must set the dwSize member of HEAPENTRY32 to
the size, in bytes, of the structure. Heap32First changes dwSize
to the number of bytes written to the structure. This will never be greater
than the initial value of dwSize, but it may be smaller. If the value is
smaller, do not rely on the values of any members whose offsets are greater
than this value.
To
access subsequent blocks of the same heap, use the Heap32Next function.
