Detailed Description

Definition of a variety of exceptions used by consmgr.

All of these are eventually descendants of std::exception.

#define PTHREAD_CHECK_AND_THROW	(	rc,
		str		)	if ((rc) != 0) throw(pthread_exception(__FILE__, __LINE__, (rc), (str)))

pthread error handling macro.

If the return-code of the pthread function ('rc') indicates a failure, construct a [temporary] pthread_exception with the relevant data in it, and throw that...

Value:

catch (pthread_exception &pe) { \
                                    std::cerr << pe.what() << std::endl; \
                                    exit((ec)); \
                                } catch (fireball &f) { \

                                } catch (...)

A define to compress the common code of dealing with exception types we've defined [above], and returned error strings. The (...) case is left to be defined for each individual try{} block.
