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():
	   Since glibc 2.19:
	       _DEFAULT_SOURCE
	   Glibc 2.19 and earlier:
	       _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.  In the event of
       an error, errno is set to indicate the cause.

ERRORS
       ENOMEM Insufficient memory to allocate passwd structure.

FILES
       /etc/passwd
	      password database file
