NAME

fgetpwent − get password file entry

SYNOPSIS

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

struct passwd *fgetpwent(FILE *stream);

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 stream must have the same format as /etc/passwd.

The passwd structure is defined in <pwd.h> as follows:

struct passwd {

char *pw_name;

			/* user name */ 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 the 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
