Detailed Description

Helper class to use files in APIs other than openmsx::File.

The openMSX File class has support for (g)zipped files (or maybe in the future files over http, ftp, ...). Sometimes you need to pass a filename to an API that doesn't support this (for example SDL_LoadWav()). This class allows to create a temporary local uncompressed version of such files. Use it like this:

LocalFileReference file(filename); // can be any filename supported // by openmsx::File my_function(file.getFilename()); // my_function() can now work on // a regular local file

Note: In the past this functionality was available in the openmsx::File class. The current implementation of that class always keep an open file reference to the corresponding file. This gave problems on (some versions of) windows if the external function tries to open the file in read-write mode (for example IMG_Load() does this). The implementation of this class does not keep a reference to the file.
