Pointer to zero terminated character string describing the failure.
Specification
Description:
An application defined call-back function that is called upon a serious, unexpected error or failure, with a descriptive message. Remember, a release version of your software should never fail.CBFnDiagFailure()void BR_CALLBACK CBFnDiagFailure(const char* message)const char * messageBrDiagHandlerSet()116). BRender has not necessarily completed initialisation. In an unknown state. A failure has occurred. BRender is not expecting the function to return.
Effects: Behaviour is up to the application, but the following procedure can be taken as a suggestion.
Set a failure condition flag (to detect escalation). Optionally, immediately inform user of failure. Re-establish a known state. Perform diagnostics of hardware and software, inform user of any diagnosed faults (optionally, also of original failure). End failure condition, and resume (do not return).
Remarks: Avoid allocating memory in your failure call-back function, or you may need special care in handling out-of-memory conditions. BRender's default failure call-back function does not allocate memory.

stddiag.c for examples of diagnostic handler functions.See Also:
