HI all,
I have a issue that when I try to write some bytes in the outputstream, I am getting the
bad access. The code is as follows :
int writtenBytes = [_os write:[packetInBytes bytes] maxLength:lengthOfPacket];
where the "packetInBytes" points to NSData and "lengthOfPacket" corresponds to the data length, and _os represents the NSOutputStream.
The call stack from the debugger is as follows :
0 0xffff0269 in __spin_lock
1 0x302a6098 in CFSocketDisableCallBacks
2 0x003b46d0 in SocketStream::write
3 0x302402c3 in CFWriteStreamWrite
4 0x0001b423 in -[Writer write:] at Writer.m:96
5 0x0001b5ef in -[Writer run] at Writer.m:111
6 0x3050a79d in -[NSThread main]
7 0x3050a338 in NSThread__main
8 0x91a27fe1 in _pthread_start
9 0x91a27e66 in thread_start**
I am not getting this issue always. I get this issue execute my code for some 5 or more times ... I have checked all the params that i pass to the write function have its values and not nil.
Any help would be greatly appreciated
Best Regards, MOhammed Sadiq.
