Structures and types defined by Allegro

There are several structures and types defined by Allegro which are used in many functions (like the BITMAP structure). This section of the manual describes their useful content from a user point of view when they don't fit very well any of the existing manual sections, and redirects you to the appropiate section when it's already described there. Note that unless stated otherwise, the contents shown here are just for read only purposes, there might be other internal flags, but you shouldn't depend on them being available in past/future versions of Allegro.
