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.
