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. 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
