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
