Why is "fun" commonly appended to the end of callback identifiers? EX, line 35 (https://github.com/LWJGL/lwjgl3/blob/master/modules/core/src/test/java/org/lwjgl/demo/stb/Image.java)I'm assuming it stands for function, but isn't that implied? Is it a holdover from another language?
It's most likely from C. There you pass actual function pointers instead of wrapping your code in separate callback classes. GLFW also uses it. (http://www.glfw.org/docs/latest/group__window.html#typedef-members)
Yes, ignore it. The "fun" postfix is part of the C type of GLFW callback functions.
Thanks. I'll probably keep fun on just for the hell of it.
