XSetCommand(3X11)   RISC/os Reference Manual    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.)

     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 non-zero status.  Other-
     wise, it returns a zero status.  To free the memory allo-
     cated to the string list, use XFreeStringList.

PROPERTIES
     WM_COMMAND
               The command and arguments, separated by ASCII
               nulls, used to invoke the application.
