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.
