Hello Saúl
Thanks for still being here :-)
If I understood correctly, I did something like this:
(inside the thread that should add a downloading request to uv_loop)
synchronized(request_queue_mutex) {
request_queue.data = curl_easy_handle;
uv_queue_work(loop, &request_queue,
[](uv_work_t* req) {},
[](uv_work_t* req, int status) {
LOG(INFO) << "working done: ";
curl_multi_add_handle(curl_handle, (CURL *) req->data);
});
}
but after running 2 simultaneous request my code breaks with:
==18186== Process terminating with default action of signal 6 (SIGABRT):
