cuserid(3S)               AT&T SYSTEM V               cuserid(3S)



NAME
     cuserid, Xcuserid - get character login name of the user

SYNOPSIS
     #include <stdio.h>

     char *cuserid (s)
     char *s;

     char *Xcuserid (s)
     char *s;

DESCRIPTION
     cuserid generates a character-string representation of the
     name associated with the effective user ID of the process.
     Xcuserid 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, [X] cuserid returns a
     NULL pointer; if s is not a NULL pointer, a null character
     (\0) will be placed at s[0].
