CUSERID(3S) — HP-UX

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 L_cuserid characters; the representation is left in this array. The constant L_cuserid 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].

BUGS

Cuserid uses getpwnam on getpwent(3C); thus the results of a user’s call to the latter will be obliterated by a subsequent call to the former.
