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 user name corresponding to the effective user ID of the process. 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].

STANDARDS CONFORMANCE

cuserid: XPG2, XPG3, POSIX.1, FIPS 151-1
