fgetpwent - get password file entry
#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
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 */
};
The fgetpwent() function returns a pointer to a 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
