libco seems pretty interesting. Do you alswo have some code to show which uses it? Just to get an idea of what you use it for typically. Have you used it with Python alreday?
The code that uses it is pretty complex (go up two folders in my gitlab link for that), so here's a minimal example of the full API:
cothread_t a, b; //cothread_t is a typedef to void*
int main() {
a = co_active(); //get a handle to the main thread
b = co_create(entrypoint, stacksize_in_bytes);
printf("a");
co_switch(b);
printf("c");
co_delete(b); //no need to delete a
}
void entrypoint() {
printf("b");
co_switch(a);
}
//output: "abc"
We've only been using it in emulators so far. It's in MESS, higan, twoMbit and a few others.
