making fgoto a no-op

[Martin Pirker]

Dear readers....

I have

%%{

action check_data {
  check_foo(......);
  fgoto *cs;     # no-op if no error occured, else stop with error
}

}%%


check_foo(.....) {
  if (........) {
    cs = machine_error;
  }
}


Question:
I can't check the data using the Ragel machine and don't
want to place the code in the action{...} definition. So I call
out to the language side, but still want to use the Ragel
error state as feedback/abort, if errors do happen.

What are (could be) the side effects of directly manipulating
cs this way or is that approach ok?


Thanks,
Martin
