Step 59 – LMSGetLastError, LMSGetErrorString and LMSGetDiagnostic

Posted on September 2, 2011 by Steve Addison

The three API functions that return information to the SCO can now be connected to the error code variable that I implemented in Step 58, and to the error messages that I set up in Step 57.

Here they are:

function LMSGetLastError() {
  return errorCode;
}

function LMSGetErrorString(thisErrorCode) {
  return errorMessages[thisErrorCode];
}

function LMSGetDiagnostic(thisErrorCode) {
  return errorMessages[thisErrorCode];
}

Pretty simple so far. Next step – testing whether variables are supported and, if so, are they readable and/or writeable.

    One quick note about this post. The SCORM 1.2 RTE specification allows the LMS developer to provide both an “error string” describing the error, and a more detailed, LMS-specific “diagnostic” message. For now, I’m simply going to use the error string text for both purposes. Time (and readers of this blog) will tell me if I need to develop more detailed diagnostic text.
