C++ (Cpp) usrrehash Examples

Example #1

static struct user *
user(uid_t uid)
{
	int i;
	struct passwd *pwd;
	struct user *usr;

	while (1) {
		for (usr = users + (uid&(nusers - 1)), i = nusers;
		     --i >= 0;
		    usr--) {
			if (!usr->name) {
				usr->uid = uid;

				if (!(pwd = getpwuid(uid)))
					asprintf(&usr->name, "#%u", uid);
				else
					usr->name = strdup(pwd->pw_name);
				if (!usr->name)
					err(1, "allocate users");
				return usr;
			} else if (usr->uid == uid)
				return usr;

			if (usr <= users)
				usr = users + nusers;
		}
		usrrehash();
	}
}
