(Lame) C OS starfield

[alkis]

Hello people.

Here is a lame starfield in C (OS friendly).
Usage: sf [numofstars] [speed]

Opens a 2 bitplane screen and places a borderless window on top of it.
Then goes to draw stars (pixels really) in 3 colors. (..of gray, dim to bright)

Press left mouse button to exit.

Adds a vertical interrupt routine to count actual frames and reports an aproximation on frames per second.

I know it's lame, but maybe it will help someone starting coding in C :-)

Laters,
/Alkis

Why do you use OpenScreenTags/OpenWindowTags which only exist in 2.0+ but then don't use AllocVec/FreeVec which would make memory handling a lot easier because you wouldn't need to remember the size you allocated?

And of course you should check for allocation failures. You check IntuitionBase, but don't do anything in case of failure. You don't check GfxBase, my_window, vbint and stars.

You check my_screen but then crash badly if it really fails because if my_screen fails to open, you close IntuitionBase but nevetheless call OpenWindowTags.
