DESCRIPTION         top

       The fgetpwent() function returns a pointer to a structure containing
       the broken out fields of a line in the file stream.  The first time
       it is called it returns the first entry; thereafter, it returns
       successive entries.  The file referred to by stream must have the
       same format as /etc/passwd (see passwd(5)).

       The passwd structure is defined in <pwd.h> as follows:

           struct passwd {
               char   *pw_name;       /* username */
               char   *pw_passwd;     /* user password */
               uid_t   pw_uid;        /* user ID */
               gid_t   pw_gid;        /* group ID */
               char   *pw_gecos;      /* real name */
               char   *pw_dir;        /* home directory */
               char   *pw_shell;      /* shell program */

RETURN VALUE         top

       The fgetpwent() function returns a pointer to a passwd structure, or
       NULL if there are no more entries or an error occurs.  In the event
       of an error, errno is set to indicate the cause.

ERRORS         top
