If you include the cmem unit in your uses clause of your program, it will replace the native Free Pascal memory manager with the C library memory manager. All memory management is then done by the C memory manager.

The unit should be the first unit in the uses clause, otherwise memory can already be allocated by initialization routines in units that are initialized before the C memory manager is installed.

There is a small example program testcmem, which demonstrates the use of the cmem unit.

CMem should not be used if heaptrc is used.
