          int                         getfh  (filename, filehandle_ptr)
          char *                      filename;

     DESCRIPTION
          If <filename> has been exported via exportfs(2), then the

          daemon.

     RETURN VALUE
          0              Successful completion. The file handle for
                         <descriptor> is returned in <filehandle_ptr>.


          -1             An error occurred.  Errno is set to indicate

     EXCEPTIONS

          EINVAL         No export entry exists for this filename.


          EFAULT         Some part of the space pointed to by
                         <filehandle_ptr> lies outside the process's
                         readable address space.
