cuserid(3S)          STANDARD I/O 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.

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].
