 Posted: Thu Nov 12, 2009 6:59 am Post subject: Problems with sceNetResolverStartNtoA() |
 |
|
I recently upgraded to 5.00m33-6 and also updated my toolchain to revision 2487.
I've been working to try and get net functionality into Lua Player Euphoria, but I'm having a hell of a time with the resolver.
I'm fairly certain this is the same code I used before, but suddenly it doesn't want to work. Specifically sceNetResolverStartNtoA() is simply hanging. It blocks the thread and never returns. Other threads continue running. I've let the thing sit for several minutes. I wrote up a quick test app to demonstrate. Is anyone aware of a change to the SDK/FW that's preventing this from working? Otherwise can anyone spot something I'm screwing up here?

Hi! :)
I had the same problem, I didn't solve it, but using the standard
| Code: | struct hostent *host;
host = gethostbyname(address); |
seems to work.
Ciaooo

Hmm... I'm getting the same behavior. ???
It tried this:
| Code: | uint32_t resolve() {
struct hostent* host = gethostbyname("google.com");
if(host == NULL) {debug("Failed to resolve host address.");}
struct in_addr* addr = (struct in_addr*)host->h_addr;
return addr->s_addr;
} |
But it hangs when it reaches gethostbyname(). This is completly bizzare.
Am I doing that lookup correctly? Still, I'd expect it to give an error rather than just sitting there like this. |
