+ This API returns the various standard system directories where apps, resources, etc get installed.
+ Because queries can return multiple directories, the API is in the form of an enumeration.
+ The directories are returned in search path order; that is, the first place to look is returned first.
+ This API may return directories that do not exist yet.
+ If NSUserDomain is included in a query, then the results will contain "~" to refer to the user's directory.
+ NEXT_ROOT is prepended as necessary to the returned values.
+ Some calls might return no directories!
+ The buffer that is passed in will be filled with a null-terminated string, possibly containing as many as PATH_MAX-1 characters.
+
+ Typical usage:
+ 
+    #include <limits.h>
+    #include <NSSystemDirectories.h>
+
+    char path[PATH_MAX];
+    NSSearchPathEnumerationState state = NSStartSearchPathEnumeration(dir, domainMask);
+    while (state = NSGetNextSearchPathEnumeration(state, path)) {
+        // Handle path
+    }
