I'm working on C++ framework and would like to apply automatic memory management to a number of core classes. So far, I have the standard approach which is class Foo { public: static shared_ptr<Foo> init() { return shared_ptr<Foo>(new Foo); } ~Foo() { } protected: Foo() { } }; // Example of use shared_...
I'm developing a program which executes a program using execvp. It needs to capture the results of the child process and parse them in the main process. It seems there is a way, using named pipes, and duping. I'm trying to hunt down a good example of this, but so far no luck. If anyone has any pointers, links and/or suggestions about thi...
I've got the following two programs, one acting as a reader and the other as a writer. The writer seems to only send about 3/4 of the data correctly to be read by the reader. Is there any way to guarantee that all the data is being sent? I think I've got it set up so that it reads and writes reliably, but it still seems to miss 1/4 of th...

Is it possible to use sockets on win32 and and not have the firewall possibly block the port you are using? Something like with unix wwere you have IF_UNIX instead of IF_INET ( named pipes instead of sockets ). I dont want to use named pipes on win32 since they are just so unreliable. ...
In PHP, I have to pass the arguments in the same order as the arguments are in the constructor. Now, in Python, take listbox = Listbox(root, yscrollcommand=scrollbar.set) for example. If I had passed yscrollcommand=scrollbar.set as the third argument and yscrollcommand was the second argument in the constructor, would I still be abl...

If a process with unicode enabled creates a named pipe, it must pass a LPCTSTR for the pipe name, in this case a LPCWSTR. Will a second process wihtout unicode be able to open that pipe by passing a LPCSTR for the pipe name? Also, can I call CreateNamedPipeW or CreateNamedPipeA and ignore whether unicode is enabled, or do I have to call...

What I'd like to know is whether using the annotation provides any advantage except for centralising quueries? In particular, is there some performances gain, for instance ...

Hi guys, I have two MFC C++ desktop applications exchanging string commands using named pipes. All good and reliable.
