/**

  • Performs a foreground decompression of the named file; does not return

  • until the decompression is complete.

*/

/**

  • Does an in-memory decompression of the indicated Ramfile. The decompressed

  • contents are written back into the same Ramfile on completion.

getProgress()

C++ Interface: get_progress(Decompressor self)

/**

  • Returns the ratio through the decompression step in the background.

/**

  • Begins a background decompression of the named file (whose filename must

  • end in “.pz”) to a new file without the .pz extension. The source file is

  • removed after successful completion.

/**

  • Begins a background decompression from the named source file to the named

  • destination file. The source file is removed after successful completion.

run()

C++ Interface: run(const Decompressor self)

/**

  • Called each frame to do the next bit of work in the background task.

  • Returns EU_ok if a chunk is completed but there is more to go, or

  • EU_success when we’re all done. Any other return value indicates an error.
