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 applica-tions applications
tions 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_SetApp-Name. Tk_SetAppName.
Name.
Tk_SetAppName is called automatically by Tk_Init, so applications don't normally need to call it
explicitly.
The command tk appname provides Tcl-level access to the functionality of Tk_SetAppName.
