cuserid(3S)         (C Programming Language Utilities)          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 file.

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

   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].
