DOSBase contains commands for working with files and directories. As Hollywood can deal
with virtual files as well as with files linked into other files like applets or executables
you must make sure that you only use IO functions provided by Hollywood in the DOSBase pointer
to deal with files. If you use functions like fopen() from the ANSI C library instead, your
plugin will only work with normal files that are physically existent on a system drive.
For example, when writing plugins that provide loaders for additional file formats like
images, sounds, or videos it can often happen that the filename that is passed to your
plugin is a specially formatted specification that Hollywood uses to load files that have
been linked to applets or executables. If you do not use Hollywood's IO functions to
open this file, your plugin won't be able to load files that have been linked to applets
or executables. This can be quite annoying for the end-user because the ability to
link data files into applets and executables is a key functionality of Hollywood and
thus your plugin should strive to be compatible with it. If you use fopen() instead,
it will just fail whenever your function is passed a specially formatted specification
to open one of Hollywood's virtual files.
DOSBase is available since Hollywood 5.0.
