C 協同程序:Coroutine
Coroutine 是 C 的協同程序。
Coroutine 支持 32 位和 64 位模式,支持 Mac OS X 和 Linux。
構建:
./build.sh
API
struct coroutine; struct coroutine *coroutine_create(void (*func)(void *), void *arg); void coroutine_delete(struct coroutine *co); struct coroutine *coroutine_self(void); int coroutine_status(struct coroutine *co); void coroutine_resume(struct coroutine *co); void coroutine_yield(void); int coroutine_getstacksize(void); void coroutine_setstacksize(int size);
Example
這是包括在 coroutine/example/example.c 里面的:
#include <stdio.h>
#include <stdlib.h>
#include <coroutine.h>
struct task {
char buffer[1024];
};
void readline(void *arg)
{
struct coroutine *co = coroutine_self();
struct task *task = arg;
while (1) {
printf("[coroutine %p] read: ", co);
if (fgets(task->buffer, sizeof(task->buffer), stdin) == NULL)
break;
coroutine_yield();
}
}
void echoline(void *arg)
{
struct coroutine *co = coroutine_self();
struct task *task = arg;
while (1) {
printf("[coroutine %p] echo: %s", co, task->buffer);
coroutine_yield();
}
}
int main(int argc, char **argv)
{
struct task task;
struct coroutine *coread = coroutine_create(readline, &task);
struct coroutine *coecho = coroutine_create(echoline, &task);
while (1) {
coroutine_resume(coread);
if (coroutine_status(coread) == COROUTINE_DEAD)
break;
coroutine_resume(coecho);
}
coroutine_delete(coread);
coroutine_delete(coecho);
return 0;
