FILE *pp;
char buf[1024];
sprintf(buf, "ls -1 %s/%s.*", PLAYER_DIR, lookup_name);
pp = popen(buf, "r");
fgets(buf, sizeof(buf), pp); // non-lossy primer read
while (!feof(pp))
{
printf("%s\n", buf2);
fgets(buf, sizeof(buf2), pp);
}
pclose(pp);
I must reiterate Jason's point, executing another program like ls from within
the MUD is really slow and kind of messy, and some people are pretty anal
about wasting cycles.
One thing to remember is that all of the shell programs like ls are
themselves written in C, so you can usually find the code out there to do
what you want without the problems inherent in calling outside programs.
