c-panic

Lightweight C module implementing panic, panic_errno, todo and unimplemented macros. The module uses fprintf and exit functions as well as stderr stream and EXIT_FAILURE macro. It also uses strerror from string.h to convert errno to string in case of panic_errno macro.

The difference between todo and unimplemented is that while todo conveys an intent of implementing the functionality later, unimplemented makes no such claims.

Usage

Simply copy the panic.h file into your project.

Examples

panic

panic("unexpected error %d", 10);

test_panic.c:5: panic: unexpected error 10

panic_errno

panic_errno("panic_errno prefix %d", 10);

panic_errno.c:7: panic: panic_errno prefix 10: Success

todo

todo("%s", "it will be implemented later");

test_todo.c:5: todo: it will be implemented later

unimplemented

unimplemented("wll %s be %s", "never", "implemented");

test_unimplemented.c:5: unimplemented: wll never be implemented
