coreleft

Returns a measure of unused RAM memory.

Defined in header <alloc.h>

Syntax

In the tiny, small,and medium models:
#include <alloc.h>
unsigned  coreleft(void);

In the compact, large, and huge models:
#include <alloc.h>
unsigned  long  coreleft(void);

Portability

Remarks

coreleft returns a measure of RAM memory not in use. It gives a different measurement value, depending on whether the memory model is of the small data group or the large data group.

Return value

In the small data models, coreleft returns the amount of unused memory between the top of the heap and the stack. In the large data models, coreleft returns the amount of memory between the highest allocated block and the end of available memory.
