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)):
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. In the event of an error, errno is set to
indicate the error.
