DESCRIPTION

       Tk_SetAppName associates a name with a given application and records  that  association  on  the  display
       containing with the application's main window.  After this procedure has been invoked, other applications
       on the display will be able to use the send command to invoke operations in the application.  If name  is
       already in use by some other application on the display, then a new name will be generated by appending “
       #2” to name;  if this name is also in use, the number will be incremented until an unused name is  found.
       The return value from the procedure is a pointer to the name actually used.

       If  the  application  already has a name when Tk_SetAppName is called, then the new name replaces the old
       name.

       Tk_SetAppName also adds a send command to the application's  interpreter,  which  can  be  used  to  send
       commands from this application to others on any of the displays where the application has windows.

       The  application's  name  registration  persists  until the interpreter is deleted or the send command is
       deleted from interp, at which point the name is automatically unregistered and  the  application  becomes
       inaccessible via send.  The application can be made accessible again by calling Tk_SetAppName.

       Tk_SetAppName  is  called  automatically  by  Tk_Init,  so  applications  do not normally need to call it
       explicitly.

       The command tk appname provides Tcl-level access to the functionality of Tk_SetAppName.
