in allegro's header file, i looked up the BITMAP structure, and it
contains two things i need to look at: height and width of the bitmap.
attached is my program, i compiled it like this:
gcc alleg2.c -o alleg2.exe -lalleg
it gives me an error:
alleg2.c: In function 'main':
alleg2.c:13: request for member 'w' in something not a structure or
union
since i looked it up myself and KNOW that BITMAPs are typedef'ed
structs, what the heII is the problem??? thanks for any help..
-- email, please!

printf( "width of bmp is %d\n", *bmp.w );
