NAME
fgetpwent - get password file entry
SYNOPSIS
#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
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 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 */ };
RETURN VALUE
The fgetpwent() function returns a pointer to a 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 | |
