I'm writing some code that is wrapping up some CFNetwork stuff to do DNS resolution in Objective-C. Everything is fine and it's working, but I have a few questions: The callback function prototype for CFHost's asynchronous resolution is passing references to CFStreamError structures even though the documentation says CFStreamError is d...
I try to load a plist file from my server. I can think of 2 ways to do that, but for both Instruments says there's huge memory leak : NSData* plistData = [NSData dataWithContentsOfURL:url]; and NSDictionary* updateDigest = [NSDictionary dictionaryWithContentsOfURL: [NSURL URLWithString:updateURL] ]; The backtrace of the memory lea...

Running on the iPhone simulator, I am listening on a port for packets, but my callback never gets called (and the packets are being sent for sure, checked with wireshark). Simplified code follows: #define IN_PORT (51112) static void ReadCallback (CFSocketRef theSocket, CFSocketCallBackType theType, CFDataRef theAddress, const void *da...
I have an application which works with sockets and reads / writes data. It uses Foundation framework combined with CFNetwork and stdio. Here is the issue - when it is launched from console (bash shell) it works 100% fine and there is nothing wrong with. However when it is invoked by another application via NSTask madness begins. The who...
Hi Stackoverflow, I know this might be not correct at all, but I'm currently getting memory leaks in Instruments while using CFReadStreamRead and CFReadStreamOpen. The code looks like this: UInt8* streambuffer = malloc(kReadStreamBufferSize); int readBytes = CFReadStreamRead(httpReadStream,streambuffer,kReadStreamBufferSize); ... free...
