Hello,
Still working on my OS. Man, OS are harder then they look.

I have a basic question. What is the best way to destroy bitmaps and fonts
in Allegro.
I have to make sure that the bitmap/font is destroyed, but I am not sure if
it exists. They are created/destroyed by apps, not the OS.

I have the following code.

// Simplified
BITMAP *B;
FONT *F;

// B may or may not be created
if (!B) destroy_bitmap(B);
if (!F) destroy_font(F);

Note: The above bitmaps/fonts may not have had a create_bitmap/ font
procedure applied to them.

Does this destroy the bitmap/font if it is created, and skip if if it isn't.
I have been doing some testing, and I am not sure, especially with the font.

I would like to use simple code like above if at all possible, I don't want
to do any other tracking of bitmaps/fonts, if I don't have to.

Any help would be great.
