About

This repo contains two similar versions of the same library. cx is another attempt to bring exceptions to C.

Comparing

aspect	cx	cx2
Required standard library functions	puts, printf	puts, printf, setjmp, longjmp
Special return type	Yes	No
Thread safe	Somewhat	Definitely no
Custom errors	Yes	Yes
User defined error handler	Yes	Yes
Trace back after exception	Yes	Yes
Signal handling	No	Yes
TRY/FIN signature	(<struct with .ex and .val>) -> value of struct	(<any code block>) -> no return

cx

Lightweight version of cx.

Minimal example

#include <cx.h>
#include <stdio.h>

void exception_handler(int err) {
    puts("Error");
}

int_ex error_function() {
    ERR(int_ex, 0);
    OK(int_ex, 2) // Not executed
}

int main() {
    set_handle(exception_handler);
    int i = FIN(error_function())
}

cx2

Fancy-pants version of cx.

Minimal example

#include <cx2.h>
#include <stdio.h>

void exception_handler(int err) {
    puts("Error");
}

int error_function() {
    ERR(0);
    return 2; // Not executed
}

int main() {
    set_handle(exception_handler);
    FIN(int i = error_function())
}
