FreeMemSys

FreeMem

Get amount of free space in current heap zone

#include <Memory.h> Memory Manager

long FreeMem( );

returns free space in current heap zone

FreeMem returns the total amount of free space, in bytes, in the current

heap zone. It usually won't be possible to allocate a single block this large

since the heap may be fragmented by locked and/or nonrelocatable blocks.

Returns: a long; the total, in bytes, of all un allocated memory in the current

heap zone.

Notes: There is another routine, FreeMemSys, which performs the equivalent

operation to FreeMem, but in the System heap zone. It takes the same

parameters as FreeMem.

FreeMem returns total free space. Use MaxBlock or PurgeSpace to

get the size of the maximum allocation you can make. Use CompactMem,

PurgeMem, or MaxMem to force a garbage collection and learn about

available allocation space.
