NAME
getpw() — get name from UID
SYNOPSIS
#include <pwd.h>
int getpw(uid_t uid, char *buf);
DESCRIPTION
getpw()
searches the password file for a user
ID
number that equals
uid,
copies the line of the password file in which
uid
was found into the array pointed to by
buf,
and returns 0.
getpw()
returns non-zero if
uid
cannot be found.
The line is null-terminated.
This routine is included only for compatibility with prior systems,
and should not be used; see
getpwent(3C)
for routines to use instead.
NETWORKING FEATURES
NFS
This routine is implemented using
getpwuid()
(see
getpwent(3C))
and therefore uses the Network Information Service
network database as described in
passwd(4).
RETURN VALUE
getpw()
returns non-zero on error.
WARNINGS
The above routine uses
<stdio.h>,
which causes it to increase, more than might be expected,
the size of programs not otherwise using standard
I/O.
Obsolescent Interfaces
getpw()
is to be obsoleted at a future date.
