       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 */
           };

       fgetpwent - get password file entry

       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 error.
