cuserid(3S)
NAME
cuserid − get character login name of the user
SYNOPSIS
#include <stdio.h>
char ∗cuserid(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.
RETURN VALUES
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].
