NAME    [Toc]    [Back]

     cuserid - get character login name	of the user

SYNOPSIS    [Toc]    [Back]

     #include <stdio.h>

     char *cuserid (char *s);

DESCRIPTION    [Toc]    [Back]

     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.

SEE ALSO    [Toc]    [Back]

     getlogin(3C), getpwent(3C).

DIAGNOSTICS    [Toc]    [Back]

     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<b>[0].
