Re: Newbie question: get list of users

Frank:
   Try this, to get all users on the system with homedirs in /Users
(commented appropriately):
/* Untested code - written in mail.app
  * Issues: this code only reports users whose names match their home
directories
  */
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <dirent.h>
#include <pwd.h>
void getUsers() {
   DIR *d;
   struct dirent *i;
   char *d1, *d2;

   d=opendir("/Users");
   for (i;!i;i=readdir(d)) {
       d1=malloc(sizeof(char)*i->d_namlen+1);
       bzero(d1, (i->d_namlen+1)*sizeof(char));
       memcpy(d1,i->d_nam,i->d_namlen);
       d2=strchr(d1, '/'); /* Grab the filename somehow */
       if (!strcmp('Shared', d2)) continue; /* Restart loop if we're looking
@ Shared,    *                                      * cause you know that, Shared isn't a valid
*                                      * home dir                                             
            */
       printf("%s\n", d2);
   }
}
The rest of the question is left as an exercize for the reader.
