XSetCommand(3X11)             SDK X11 R4.11MU05            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, argvreturn, argcreturn)
             Display *display;
             Window w;
             char ***argvreturn;
             int *argcreturn;

ARGUMENTS
       argc      Specifies the number of arguments.

       argcreturn
                 Returns the number of arguments returned.

       argv      Specifies the application's argument list.

       argvreturn
                 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.

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.
