     XSetCommand(3X11)   X Version 11 (Release 5)    XSetCommand(3X11)



     NAME
          XSetCommand, XGetCommand - set or read a window's WM_COMMAND
          property

     SYNTAX
          XSetCommand(display, w, argv, argc)
                Display *display;
                Window w;
                char **argv;
                int argc;

          Status XGetCommand(display, w, argv_return, argc_return)
                Display *display;
                Window w;
                char ***argv_return;
                int *argc_return;

     ARGUMENTS
          argc      Specifies the number of arguments.

          argc_return
                    Returns the number of arguments returned.

          argv      Specifies the application's argument list.

          argv_return
                    Returns the application's argument list.

          display   Specifies the connection to the X server.

          w         Specifies the window.

     DESCRIPTION
          The XSetCommand function sets the command and arguments used
          to invoke the application.  (Typically, argv is the argv
          array of your main program.)  If the strings are not in the
          Host Portable Character Encoding the result is
          implementation dependent.

          XSetCommand can generate BadAlloc and BadWindow errors.

          The XGetCommand function reads the WM_COMMAND property from
          the specified window and returns a string list.  If the
          WM_COMMAND property exists, it is of type 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 nonzero status.
          Otherwise, 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,

     PROPERTIES
          WM_COMMAND
                    The command and arguments, null-separated, used to
                    invoke the application.

     DIAGNOSTICS
          BadAlloc  The server failed to allocate the requested
                    resource or server memory.

          BadWindow A value for a Window argument does not name a
                    defined Window.
