Hi.  I'm writing some C code that will run on a couple of machines, and I'd  
like to use the mstats() function to get a report on how much mamory has been  
malloc'd.   But it doesn't work like the man page says it should; in fact, it  
doesn't seem to do anything.  It prints nothing and always seems to return 1.

The man page says:
     Mstats prints a summary of memory usage by malloc on stderr.
     The efficiency value is calculated based on the rounded-off
     block sizes, and is the ratio of the space available in the
     blocks to the total amount of memory allocated by malloc.
     The value returned is the total amount of memory allocated,
     in bytes.
But this program prints the output that follows:
     #include <stdlib.h>
     #include <stdio.h>
     
     int main (int argc, char *argv[])
     {
       char *buf;
       size_t m_result;
       
       if ( (buf = malloc(30)) == NULL ) {
	 fprintf(stderr, "error: malloc failed\n");
	 exit(1);
       }
       m_result = mstats();
       printf("mstats returns: %ld\n", (long) m_result);
     
       if ( (buf = malloc(1000)) == NULL ) {
	 fprintf(stderr, "error: malloc failed\n");
	 exit(1);
       }
       m_result = mstats();
       printf("mstats returns: %ld\n", (long) m_result);
     }

OUTPUT:
mstats returns: 1
mstats returns: 1

Any suggestions?   I know about MallocDebug, but I'm not really writing a  
NeXTstep application or using IB.
