getpw(3C)

NAME
     getpw - get name from UID

SYNOPSIS
     #include <stdlib.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.

     This routine is included only for compatibility with prior systems and
     should not be used; see getpwent(3C) for routines to use instead.

FILES
     /etc/passwd

SEE ALSO
     getpwent(3C), passwd(4).

DIAGNOSTICS
     getpw returns non-zero on error.

WARNING
     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.
