Mac OSX Deprecated API - FSRef ref;

Question

I have the following code that compiles on Pre OSX 10.13 machines

  FSRef ref;
  OSType folderType = kApplicationSupportFolderType;
  char path_c[PATH_MAX];
  FSFindFolder(kUserDomain, folderType, kCreateFolder, &ref);
  FSRefMakePath( &ref, (UInt8*)&path_c, PATH_MAX);

I need this to work on the latest versions. How can I change this? It currently says such an API does not exist

The modern equivalent requires Objective-C(++) or Swift. In Objective-C, it would be:

NSFileManager *fm = [NSFileManager new];
NSURL *url = [fm URLForDirectory:NSApplicationSupportDirectory
                        inDomain:NSUserDomainMask
               appropriateForURL:nil
                          create:YES
                           error:NULL];
char path_c[PATH_MAX];
[url getFileSystemRepresentation:path_c maxLength:sizeof(path_c)];

I don't know exactly how you will use path_c . If you only need a pointer to a C string for the path and it won't be used after the url object has been released, you could use url.fileSystemRepresentation , instead. Even better, switch to using APIs that take URLs rather than path strings, where possible.
