+The function os_file_dirname returns a directory component of a
+null-terminated pathname string.  In the usual case, dirname returns
+the string up to, but not including, the final '/', and basename
+is the component following the final '/'.  Trailing '/' charac­
+ters are not counted as part of the pathname.
+
+If path does not contain a slash, dirname returns the string ".".
+
+Concatenating the string returned by dirname, a "/", and the basename
+yields a complete pathname.
+
+The return value is  a copy of the directory component of the pathname.
+The copy is allocated from heap. It is the caller responsibility
+to free it after it is no longer needed.	
+
+The following list of examples (taken from SUSv2) shows the strings
+returned by dirname and basename for different paths:
