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;
}
SSSSEEEEEEEE AAAALLLLSSSSOOOO
catch(3), error(3), error_handler(4)
