GETPWENT(3)  —  UNIX Programmer’s Manual

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;

setpwent()

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
/etc/yp/domainname/passwd.byname
/etc/yp/domainname/passwd.byuid

SEE ALSO

getlogin(3), getgrent(3), passwd(5), ypserv(8)

DIAGNOSTICS

Null pointer (0) returned on EOF or error. 

BUGS

All information is contained in a static area so it must be copied if it is to be saved.
