After loading from memory, does SFML assume possession of the buffer data, or is it safe to delete it? The documentation says nothing, which leads me to assume it can be deleted, but I want to make sure.

If you delete the image then you no longer can use it.

What do you mean by delete exactly ?

I mean like this:

Code: [Select]

char* buffer = ...;
size_t size = ...;

sf::Font font;
font.LoadFromMemory(buffer, size);

// Is it safe for me to delete the buffer now?
free(buffer);

This is true for images or sound buffers for not for fonts. A font cannot be 100% loaded from its source (it may define thousands of characters, and I don't include the various styles and sizes). So the font data must be kept in memory as long as the font is used.

Thank you! I think you should add this bit of information to the documentation. :)

It's already done in the SFML 2 documentation.
