NAME

cuserid - get character login name of the user  

SYNOPSIS

#include <stdio.h>

char *cuserid(char *s);  

DESCRIPTION

The cuserid() function generates a character-string representation of the login name under which the owner of the current process is logged in. If s is a null pointer, this representation is generated in an internal static area whose address 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.

In multithreaded applications, the caller must always supply an array s for the return value.  

RETURN VALUES

If the login name cannot be found, cuserid() returns a null pointer. If s is not a null pointer, the null character `\0' will be placed at s[0].
