NAME
     tt_error - Interpose a function to  detect  errors  returned
     from the ToolTalk API.

SYNOPSIS
     #include <Tt/tt_c.h>
     void tt_error ( const char *funcname, Tt_status status );

DESCRIPTION
     The tt_error() function is a publicly-known  null  function.
     This functions is called by the ToolTalk library just before
     it returns from any ToolTalk API  call  that  has  a  status
     other  than TT_OK. The name of the function that is about to
     return and the status code is passed.

     You can use this call to set a dbx breakpoint in tt_error to
     quickly  catch  and  trace back any ToolTalk errors. You can
     also interpose this function, for example, to  log  ToolTalk
     errors to stderr.

APPLICATION USAGE
     The following code example shows how  an  application  might
     interpose this function to log ToolTalk errors to stderr

               void tt_error(const char *funcname, Tt_status status) {
                    fprintf(stderr, "ToolTalk function %s returned %s.\n",
                         funcname, tt_status_message(status));
               }
