DESCRIPTION
     These procedures may be used to manipulate the current work-
     ing  directory  for  the  application.  They provide C-level
     access to the same functionality as the Tcl pwd command.

     Tcl_GetCwd returns a pointer  to  a  string  specifying  the
     current  directory,  or  NULL if the current directory could
     not be determined.  If NULL is returned, an error message is
     left  in the interp's result.  Storage for the result string
     is  allocated   in   bufferPtr;   the   caller   must   call
     Tcl_DStringFree()  when the result is no longer needed.  The
     format of the path is UTF-8.

     Tcl_Chdir changes the applications current working directory
     to the value specified in path.  The format of the passed in
     string must be UTF-8.  The function returns -1 on error or 0
     on success.
