Re: Getting the current user dir in Carbon

If you are using Mach-O and don't mind slipping in a tiny bit of Objective-C, there's a pretty simple way to get what you want:

const char *path = [[@"~/lib" stringByStandardizingPath] fileSystemRepresentation];

If you use this technique in a Carbon app, you will need to bracket this code with an autorelease pool. If you don't know what this means, here are the Cliff's Notes:

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
const char *path = [[@"~/lib" stringByStandardizingPath] fileSystemRepresentation];
[pool release];

Yeah - I reckon I could do that but MoreFilesX's DeleteLevel routine says to first check the file manager's name attribute bit to see if POSIX names are required - and in this case Gestalt reports that POSIX names are required.........

I can't believe with all the POSIX code in the universe there is not some simple standard way of denoting the current user's home folder in path names.

I'll give your approach a try as a last-ditch effort. Thanks.

Have you considered using the Carbon approach:

    FSRef    userFolder;
    OSErr    err = FSFindFolder( kUserDomain, kCurrentUserFolderType,
kDontCreateFolder, &userFolder );

if ( err == noErr )
{
    FSRef   lib;
    UniChar name[] = { 'l', 'i', 'b' };
    err = FSMakeFSRefUnicode( &inParentFSRef, 3, name,
kTextEncodingDefaultFormat, &lib );
  // Delete lib.

}

 My code basically looks like this, "lib" being the dir inside the
 current user's dir that I want to delete:

 UInt8    *userslibPathPOSIX = "./lib";

 I've tried:

 UInt8    *userslibPathPOSIX = "./lib";

 and

 UInt8    *userslibPathPOSIX = "~/lib";

 and

 UInt8    *userslibPathPOSIX = "Users/~/lib";

 and

 UInt8    *userslibPathPOSIX = "$HOME/lib";

 None of them work.

I believe it is "~". "." is the current working directory, which

directory.

 Isn't the current user directory just specified as "."?

 Ian

This may be a newbie question, but how do I specify the current
user directory using a POSIX-style pathname in Carbon? I need to
delete a directory directly inside the current user directory so I
need to make a fixed path as a POSIX pathname string and then
convert it to an FSRef.

 Thanks,
