cuserid(3S)             LIBRARY FUNCTIONS             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 Lcuserid characters; the representation is left
     in this array.  The constant Lcuserid  is  defined  in  the
     <stdio.h> header file.

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].
