int _stdcall gzip_writefile(char* path,void* buf,DWORD size) - writes a memory block to a GZIP file - in_midi calls it from file info box
|
||
|
|
|
||
|
|
other hacks:
|
||
|
|
recent versions understand file://... urls, can do partial file access (eg. "partial://00006666-66660000:c:\foo\bar.dat\zzz.wav" (zzz.wav is the "display name" + extension to make winamp select correct plug-in) and auto-detect CD drive letter (eg. #:\x.mp3 will scan all drives for that file; also works with partial:// )
|
||
|
|
you can (for an example) build a playlist which will play Unreal soundtrack directly from the game CD on any system
|
||
|
|
latest read_file.dll is bundled with the midi plug-in: http://www.blorp.com/~peter/zips/in_midi.zip
