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

CONFORMING TO
