FGETPWENT(3)               Linux Programmer's Manual              FGETPWENT(3)

NAME
       fgetpwent - get password file entry

SYNOPSIS
       #include <stdio.h>
       #include <sys/types.h>
       #include <pwd.h>

       struct passwd *fgetpwent(FILE *stream);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fgetpwent(): _SVID_SOURCE

DESCRIPTION
       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
       The  fgetpwent()  function  returns a pointer to a passwd structure, or
       NULL if there are no more entries or an error occurs.

ERRORS
       ENOMEM Insufficient memory to allocate passwd structure.

FILES
       /etc/passwd
              password database file
