OpenInputCompressedFile

int OpenInputCompressedFile( ZFILE * ifp, long fn );

Description

Opens a file for input. This function sets up the LZ compression algorithm window associated with the ZFILE file. The second parameter is the file handle (FS2) or address (#zimport) of the input file to be opened. If the file is already compressed, after calling this function the file can be decompressed by calling ReadCompressedFile(). If the file handle points to an uncompressed FS2 file, after calling this function the resulting ZFILE file can be compressed by calling CompressFile().

The INPUT_COMPRESSION_BUFFERS macro controls the memory allocated by this function. It defaults to 1.
