Description
  XGetCommand()  reads the XA_WM_COMMAND property from the specified window and returns a string list.	If the XA_WM_COMMAND property exists,
  it is of type XA_STRING and format 8.  If sufficient memory can be allocated to  contain  the  string  list,	XGetCommand()  fills  in  the
  argv_return and argc_return arguments and returns a non-zero status.	If the data returned by the server is in the Latin Portable Character
  Encoding, then the returned strings are in the Host Portable Character Encoding.  Otherwise, the result is implementation-dependent.	 Oth-
  erwise,  it  returns	a  zero  status.   If  the data returned by the server is in the Latin Portable Character Encoding, then the returned
  strings are in the Host Portable Character Encoding.	Otherwise, the result is implementation-dependent.  To free the memory	allocated  to
  the string list, use XFreeStringList().
