OSSP ex is a small ISO-C++ style exception handling library for use in the ISO-C language. It allows you to use the paradigm of throwing and catching exceptions in order to reduce the amount of error handling code without making your program less robust. This is achieved by directly transferring exceptional return codes (and the program control flow) from the location where the exception is raised (throw point) to the location where it is handled (catch point), usually from a deeply nested sub-routine to a parent routine. All intermediate routines no longer have to make sure that the exceptional return codes from sub-routines are correctly passed back to the parent.
