Standard C Library Functions                          cuserid(3C)



NAME
     cuserid - get character login name of the user

SYNOPSIS
     #include 

     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 Lcuserid characters; the represen-
     tation is left in this  array.  The  constant  Lcuserid  is
     defined in the  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
     `\0' will be placed at s[0].
