Coroutine

Coroutine

####Status

• a basic C89 implementation is now in place with the following caveats:
• linux implementation is achieved through ucontext.h, which isn't the best idea...
• windows implementation is mature enough that I use it daily in my own projects... but no guarantees!

Introduction

A portable (sorta) library for coroutines!

The plan is to have both a barebone C89 library and a C++11 wrapper on top for advanced features.

To try it out now, simply copy the source code in ./clib/src/ and put #include "coroutine.h" in the desired file.

A Simple Example

###C89

cordata_ptr g_cor;

void foo1(void_ptr data) {
    int i;
    int *num = data;

    for (i = 0; i < 10; ++i) {
        ++*num;
        printf("foo1: %d\n", i);

        cor_call(g_cor, NULL);
    }
}

int main() {
    int i;
    int stuff = 0;
    corparam param;

    g_cor = cor_init(&stuff);

    param.stack_size = 0;
    param.data       = &stuff;

    cordata_ptr cor_foo = cor_new(foo1, &param);
    
    for (i = 0; i < 10; ++i) {
        printf("main: %d and %d\n", i, stuff);
        cor_call(cor_foo, NULL);
    }

    cor_del(cor_foo);
    cor_del(g_cor);

    return 0;
}

###C++11
