Check out getrusage().  It looks like you can get all the info from ps 
with this call.  I've never used it, but I think you would do something 
like this:

#include <sys/time.h>
#include <sys/rusage.h>

void show_usage(struct char_data * ch)
  struct rusage *usage;
  int page_size, usage_kbytes;
  char buf[1024];

  if((page_size = getpagesize() < 0) {
    send_to_char("Error attempting to get page size.\r\n", ch);
  else if((getrusage(RUSAGE_SELF, usage)) < 0) {
    send_to_char("Error attempting to get usage information.\r\n", ch);

  usage_kbytes = usage->ru_maxrss * page_size / 1024;

  sprintf(buf, "Current memory usage is %ik\r\n", usage_kbytes);
  send_to_char(buf, ch);
  free(usage); /* don't know if this is necessary */

This probably won't work as written, but it's a start :)
