unless parent is asking about malloc'd space, then mallinfo() or

interesting didn't know that..
though now I have a question about it ..
#include <malloc.h>
#include <stdio.h>
#include <stdlib.h>
int main(){
char *foo;
printf("total free space: %d\n",mallinfo().fordblks);
foo=malloc(500000);
if(foo){
printf("successfully allocated!\n");
} else {
printf("error allocating!\n");
}
printf("arena: %d\n",mallinfo().arena);
printf("ordblks: %d\n",mallinfo().ordblks);
printf("max total allocated space: %d\n",mallinfo().usmblks);
printf("total allocated space: %d\n",mallinfo().uordblks);
printf("total free space: %d\n",mallinfo().fordblks);
return 0;
}
outputs:
total free space: 0
successfully allocated!
arena: 0
ordblks: 1
max total allocated space: 0
total allocated space: 0
total free space: 0
If I allocate 50000bytes then it outputs:
total free space: 0
successfully allocated!
arena: 184320
ordblks: 1
max total allocated space: 0
total allocated space: 50008
total free space: 134312
does anyone have an explanation for that?
