sf::InputStream newb question
« on: September 08, 2011, 10:33:24 pm »
Hello, trying to create an InputStream to be able to load files directly from my custom packaging format, but i get a segmentation fault on the Read function.

EDIT; Well what i really wanted to ask what; What is the basic principles of getting sometihng like this to work ? :D

Warning: I have no or very little knowledge of what I am actually doing here, but here goes the sourcecode;

Cpp;

Hpp;

my::Data::File::GetContents() returns a char* containing  raw filedata.

Could you please provide a complete and minimal source code that reproduces the problem, so that I can test and debug it?

You don't know how to reduce your code? It looks simple: provide your InputStream class, and a main that uses it to load a resource. Replace your Data::File class with a std::vector<char>, for example.

I didn't know how to write the functions properly, however i made it work just now. Apparently one of my functions was broken, stupid mistake :P

Was it a mistake in my::Data::Stream (in this case I'd like to see the fix) or somewhere else in your code?

Somewhere else in my code, my::Data::Package::GetFile returned empty pointers for some reason :S created a my::Data::Package::GetStream instead and now it works fine!

The code that I went with:http:// https://legacy.sfmluploads.org/code/88
