The information in this article applies to:
- The C Run-time (CRT), included with:
- Microsoft C/C++ for MS-DOS, version 7.0
- Microsoft Visual C++ for Windows, versions 1.0 and 1.5
----------------------------------------------------------------------
The virtual memory functions in the Microsoft C Run Time libraries always
use a far heap for managing internal information. The far heap is used for
keeping a log of free memory blocks and consists of a series of 12-byte
blocks.
If you are analyzing heap use with _heapwalk() in a small- or medium-
memory model application, this information is hidden. However, _fheapwalk()
correctly reports use of the far heap.
Using _vheapterm() to terminate the virtual memory manager frees any memory
allocated for the virtual memory manager; therefore, the far heap is freed
for applications that have a single data segment.
