Re: Names of drives (was Re: A little help for a Mac newbie? :-))

I thought I was remembering a way to get this from Java without resorting to native of some sort. Since no one has indicated it yet. If you are dealing with Carbon API's that expect Classic type paths you will at some point need to do the translation as Glen indicated.

What I do JNIDirect, you could probably translate to JNI if you're familiar with that is...

if (abspath.indexOf("/Volumes/") > -1) // A non-boot path?
sErr = set(abspath.substring(abspath.indexOf("/Volumes/") + 9),this);
else sErr = set(File.separator + bootvol() + file.getAbsolutePath(),this);

bootvol() ends up calling...

public synchronized static String getSysVolName() {
short err;
short [] vRefNum = new short[1];
try {
// JDirectLocking.acquire();
err = macnative.jnidirect.MoreFileUtils.getSysVolume(vRefNum);
if (err != (short)0) throw new NullPointerException("FSSpec: Unable to obtain system volume - FindFolder" + err);
char [] name = new char[256];
err = FSGetVolumeInfo(vRefNum[0],0,0,0,0,name,0);
short strlen = (short)name[0];
return new String(name,1,strlen);
}
catch (Exception ex) { ex.printStackTrace(); return null; }
// finally { JDirectLocking.release(); }
}

////////////////////////////////////////////////////////////
// GetSysVolume //
// Get the vRefNum of the system (boot) volume //
////////////////////////////////////////////////////////////
public static short getSysVolume(short [] vRefNum) {
int [] dir = new int[1];
try {
// CarbonLock.acquire();
return FindFolder(kOnSystemDisk,kSystemFolderType,false,vRefNum,dir);
}
finally { /* CarbonLock.release(); */ }
}
