Threadsafe Code
All BSFNs created for JD Edwards EnterpriseOne 8.11 Applications Release and earlier Applications releases are designed to run in a single-threaded environment. BSFNs designed for JD Edwards EnterpriseOne 8.11 SP1 Applications Release and later Applications releases that also run with JD Edwards EnterpriseOne Tools Release 8.96 and later Tools releases are designed to run in a multi-threaded environment. To be considered threadsafe, BSFNs cannot use:
Global variables.
Static variables.
External declarations.
Non-threadsafe ANSI C APIs.
Safety Check is a source code analysis tool that scans C source code and header files for non-threadsafe behaviors. Given a source or header file, Safety Check finds all instances of non-threadsafe code, returning line numbers and code fragments.
Several non-threadsafe APIs have a JD Edwards EnterpriseOne replacement. These replacement APIs have the same parameters as the non-threadsafe C APIs, except where noted. Most non-threadsafe APIs do not have a JD Edwards EnterpriseOne replacement. These APIs and their replacements do not necessarily have the same parameters. Use care when using these APIs.
This table lists the non-threadsafe C APIs for which SafetyCheck searches, the threadsafe standard C replacements, and the threadsafe JD Edwards EnterpriseOne replacements (if applicable):
