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);
return;
}
else if((getrusage(RUSAGE_SELF, usage)) < 0) {
send_to_char("Error attempting to get usage information.\r\n", ch);
return;
}
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 :)
