This function allows error information to be logged using a user-defined callback routine.
The callback routine is invoked IMMEDIATELY; it is not a "callback" in the ordinary use of that word. The callback routine is invoked with error information in the context allowing the user to do application-specific handling (for example, it can be written to an error log or a Window display). After invoking the callback, this method will invoked rtxErrFreeParms to free memory associated with the error information.
The prototype of the callback function to be passed is as follows:
int cb (const char* ptext, void* cbArg_p);
where ptext is a pointer to the formatted error text string and cbArg_p is a pointer to a user-defined callback argument.
