CUSERID(3S) (C Programming Language Utilities) CUSERID(3S)
NAME
cuserid - get character login name of the user
SYNOPSIS
#include <stdio.h>
char *cuserid (s)
char *s;
DESCRIPTION
cuserid generates a character-string representation of the
login name that the owner of the current process is logged
in under. If s is a NULL pointer, this representation is
generated in an internal static area, the address of which
is returned. Otherwise, s is assumed to point to an array
of at least Lcuserid characters; the representation is left
in this array. The constant Lcuserid is defined in the
<stdio.h> header file.
DIAGNOSTICS
If the login name cannot be found, cuserid returns a NULL
pointer; if s is not a NULL pointer, a null character (\0)
will be placed at s[0].
