Super Catch

Cross-platform catch (almost) any error (signal, structured exception, system error), converting it to std::exception. Using original C++ try-catch syntax.

Usage

#include <super_catch.h>

int main() {
    SUPER_TRY {
        // Trigger segmentation fault
        std::unique_ptr<TestClass> test;
        test->TestMethod();
    } SUPER_CATCH (const std::exception &e) {
        fprintf(stderr, "super catched exception: %s\n", e.what());
    }
}

See test/main.cpp for detail.

Feature

• Original C++ try-catch syntax. (SUPER_TRY, SUPER_CATCH)
• Convert all types of system errors (SEH, signal) to std::exception
• Supports Windows with MSVC compiler (needs /EHa compiler flag)
  • Structured Exceptions
  • Signals (SIGABRT, SIGSEGV, SIGFPE)
• Supports POSIX compatible systems
  • Signals (SIGILL, SIGABRT, SIGFPE, SIGTRAP, SIGSEGV, SIGBUS, SIGPIPE, SIGTERM)

Limitation

• macOS: When invoking code which address is at non-executable segments, the SIGSEGV won't be captured by signal handler.
• Windows: Unsure about the behaviour if the compiler is clang-cl (likely won't work) or compiling in mingw environments with POSIX api.
• The recover code won't release locks, use with cautious when the code contains lock.
• The recover code won't destruct C++ objects like std::unique_ptr, use with cautions if the code allocates memory.
