Error Conditions: Introduction

---

Errors reported by Sites tags are stored in the variable named errno. The errno page describes all possible values of errno.

Each tag sets the value of errno. Therefore, check the value of errno immediately after calling the tag.

It is good programming practice to set the value of errno to 0 prior to calling a tag.

Errors in revision tracking, BlobServer, and EvalServer are stored in the variable named errdetail.

 

Note To support the standard J2EE JNDI interface, any of the directory tags may cause any directory error to be set. Directory tag client code should gracefully handle all of the error codes described in this document for any tag call.
