Exception.h File Reference

Detailed Description

This file provides the root of the exception hierarchy. The goal of this hierarchy is to provide the most possible information on what caused the exception at the least possible cost for the programmer.

Every exception is the descendent of Exception that, in turn, extends the std::exception class of the STL.

Further descendents of Exception add functionality and automatisms to error message generation:

Example exception raising:

            void MyFile::open(const char* fname) throw (FileException)
                  if ((fd = open(fname, O_RDONLY)) == -1)
                        throw FileException(errno, stringf::fmt("opening %s read-only", fname));

Example exception catching:

      try {
            } catch (FileException& e) {
                  fprintf(stderr, "%.*s: aborting.\n", PFSTR(e.toString()));
