Here's a snippet to query memory consumption from heap or arena.

Cheers

/* Query the application's memory utilization */

#include <sys/types.h>
#include <malloc.h>
#include "tectonics.h"

int
BytesUsedHeap( void )
{
    struct mallinfo mi;

    mi = mallinfo();
    return( (int)(mi.usmblks + mi.uordblks) );
}

int
BytesUsedArena( void *arena )
{
    struct mallinfo ami;

    if (arena == NULL) return( 0 );
    ami = amallinfo( arena );
    return( (int)(ami.usmblks + ami.uordblks) );
}
