struct passwd *fgetpwent(FILE *stream); 

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 */
};

The fgetpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs.

ENOMEM	Insufficient memory to allocate passwd structure.

/etc/passwd
	password database file
