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, use XFreeStringList.
