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
