cuserid(3C)						   Standard C Library Functions 					       cuserid(3C)

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 `' will be placed at
       s[0].
