4.3.1.9 Plugin Discovery

At program launch time, SCF discovers plugins automatically by searching a set of directories, and creates an internal database associating available SCF class names with the plugin modules which implement them. The directories which SCF searches by default are:

• The application resource directory as returned by csGetResourceDir(). On most platforms, this is the same as the directory containing the application, however, on MacOS/X, it is the `Resources' directory within the Cocoa application wrapper.
• The directory containing the application (or containing the Cocoa application wrapper for MacOS/X) as returned by csGetAppDir().
• The installed Crystal Space resource directories as returned by csGetConfigPath(). This is often the value of the `CRYSTAL' environment variable, or the `CrystalSpaceRoot' default setting on MacOS/X (which is often stored within the `NSGlobalDomain' domain).

If you would like SCF to scan additional directories, you can invoke either of these two functions:

• scfInitialize (csPluginPaths const*)
• iSCF::ScanPluginsPath(char const*, bool, char const*)

Finally, if need to manually register a single plugin module with SCF for which you know the native pathname (not a VFS pathname), you can invoke iSCF::RegisterPlugin().
