Stack Size

[Wisely Done]

Hello, I would like to ask how much in average is the stack size ?

I would like to create a simple game using SFML, and I wonder if I should allocate memory on the heap for images.

Last time I checked, it's 1MB. I've seen an option somewhere in Visual Studio where you can change the default stack size.

Normally, images are quite large, even smaller ones; far too big to be placed on the stack. Your best bet is to allocated such resources on the heap.

Should I reserve like 10 MB for stack size and avoid dynamic memory allocation ?

It's possible to reserve a stack of that size, but only in Visual Studio. Besides, you're better off using the heap.
I suggest either implementing a linked-list, or allocating a pool of memory, and placing a resource inside the pool.

If you create a sf::Image on the stack only sizeof(sf::Image) bytes will be stored on the stack. The actual pixel data will be stored on the heap so it's probably not much to worry about.
