如何使用lua c api创建lua协程？

#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

lua_State *L = luaL_newstate();

luaL_openlibs(L);

lua_State *co = lua_newthread(L);

const char *code = "function myCoroutine() print('Hello from coroutine') end";
int result = luaL_loadstring(co, code);
if (result != LUA_OK) {
    const char *errorMsg = lua_tostring(co, -1);
    printf("Error loading Lua code: %s\n", errorMsg);
    return;
}

result = lua_resume(co, NULL, 0);
if (result != LUA_OK && result != LUA_YIELD) {
    const char *errorMsg = lua_tostring(co, -1);
    printf("Error running Lua coroutine: %s\n", errorMsg);
    return;
}
