|
Did anyone figure out how to perform async wifi io?
Can it perhaps be done by splitting optixx's curl based net_io read routine in a read_async and a read_wait part ? If yes, where shall the cut point be?
| Code: |
int net_io_read( netfd *fd, void *read_buffer, int size )
{
char url[512];
int ret;
if (!fd){
printf("net_io_read: invalid fd\n");
fprintf(stderr,"net_io_read: invalid fd\n");
return -1;
}
snprintf(url,511,"http://%s/read?fd=%i&size=%i",net_io_uri,fd->fd,size);
if (net_io_debug)
fprintf(stdout,"net_io_read: url=%s\n",url);
curl_easy_setopt(fd->curl, CURLOPT_URL, url );
curl_easy_setopt(fd->curl, CURLOPT_WRITEFUNCTION, callback_read);
(void) sceKernelWaitSema(__net_io_state.sema_read, 1, 0);
__net_io_state.read_offset = 0;
__net_io_state.read_buffer = read_buffer;
fd->res = curl_easy_perform(fd->curl);
ret = __net_io_state.read_offset;
(void) sceKernelSignalSema(__net_io_state.sema_read,1);
if (fd->res != CURLE_OK) {
printf("net_io_read: %s\n", curl_easy_strerror(fd->res));
fprintf(stderr,"net_io_read: %s\n", curl_easy_strerror(fd->res));
return -1;
}
curl_easy_getinfo(fd->curl,CURLINFO_SPEED_DOWNLOAD,&fd->speed);
__net_io_state.read_speed = fd->speed;
return ret;
}
