NAME

throw() - forces an error to occur in an object.

SYNOPSIS

void throw(mixed);

DESCRIPTION

The  throw()  efun may be used to force an error to occur in an object.
When used in conjunction, throw() and catch() allow the  programmer  to
choose  what  error  message  is displayed when a runtime error occurs.
When throw() is used,  it  should  be  used  in  conjunction  with  the
catch(3) efun.  Here is a typical usage:

string err;
int rc;

err = catch(rc = ob->move(dest));
if (err) {
throw("move.c: ob->move(dest): " + err + "\n");
return;
}
