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.
