I made a memory leaking application to see what would happen if I dynamically allocated an array with zero elements in it. I had it so that it would create the zero length array a thousand times. Every time I did this the application leaked about sixteen KB of memory. I then modified the program to ...

If you allocate a block of memory, such as an array of five integers. How does the system know how much memory to free up when you call delete[]? And if you did something like this int *intArray = new int[0]; delete[] intArray; would "new int[0]" actually reserve anything (like even a memo...

As someone who's currently studying the win32 api, I'd just like to mention this. A common theme I've seen in a few apis I've looked at is to use typedef to make the api easier to understand. For example, the GetMessage function returns BOOL. BOOL is really just a typedef of int. That way in additio...

One application that wouldn't require a gui but would still be useful would be a simple image format converter. you could have it so that the app takes a 24 bit bitmap (or any other image formats you know how to work with) and outputs a 32 bit image. This is useful for people who need an alpha chann...

wearymemory I can't thank you enough.

I've spent the last few weeks trying to study win32 programming and the hardest part has been finding any useful reference material. Right now I mainly want to focus on UI objects like buttons, text fields, etc. I can usually find the correct window classes for these objects but I'm having a lot of ...

I just started learning about the windows message loop and how to use the functions GetMessage and PeekMessage. While I was making a test application using GetMessage for the message loop I had trouble getting the program to close. When I use the following message loop / Window Procedure, GetMessage...

thanks!

well... it would probably actually be faster to store that data locally, rather than having to call an OpenGL function, which would then ask the GPU for the data, and then wait for the GPU to send it back. If you want, here's a semi-general template for a Texture class: class Texture { unsigned id;...

I don't believe there is one; texture coordinates are provided in a [0,1] range. However, if you really want the original width and height, you can store it before you call glTexImage2D (you need the width and height to call it anyway), and then use it later. I was really hoping that I wouldn't hav...

Is there any function(s) in openGL that would allow you to the the width and height of a texture that was sent to it?

I'm sorry everyone I guess I've been asking the wrong question. what I'm trying to find out is how literals are stored in memory. IIRC they're usually stored on the stack. Sometimes the compiler may optimize it differently, but that is (I think) the general case. There is no need to worry about mem...

let me rephrase my first question a little bit. void someFunction(char* string); int main() { someFunction("this is a string"); return 0; } how is the string literal "this is a string" handled in memory? Is it allocated as part of the main function or is memory dynamically alloca...
