GETPWENT(3)

NAME
getpwent, getpwuid, getpwnam, setpwent, endpwent - get password file entry

SYNOPSIS
#include <pwd.h>

struct passwd *getpwent();

struct passwd *getpwuid(uid) int uid;

struct passwd *getpwnam(name) char *name;

int setpwent();

int endpwent();

DESCRIPTION
Getpwent, getpwuid and getpwnam each return a pointer to an object with the following structure containing the broken-out fields of a line in the password file.

The fields pw_quota and pw_comment are unused; the others have meanings described in passwd(5).

Getpwent reads the next line (opening the file if necessary); setpwent rewinds the file; endpwent closes it.

Getpwuid and getpwnam search from the beginning until a matching uid or name is found (or until EOF is encountered).

FILES
/etc/passwd

SEE ALSO
getlogin(3), getgrent(3), passwd(5)

DIAGNOSTICS
Null pointer (0) returned on EOF or error.
