This file contains classes for creating cleanup objects and exceptions derived from standard library runtime error.

Macro Definition Documentation

#define CMR_CATCH_PRINT_THROW	(		msg,
			new_ex
	)

Value:

catch(const std::exception &e)  \
  { std::cerr << e.what() << " " << msg << ".\n"; throw new_ex; }

Macro for handling errors in function with multiple failure points.

Suggested usage: This macro should be used in a function by initially declaring a runtime_error new_ex("Function failed."). Then, for various smaller tasks within the function that may throw for distinct reasons (and which throw exceptions derived from std::exception), use a try block followed by CMR_CATCH_PRINT_THROW("description of failure in small task", new_ex).
