#include <tk.h> Tk_ErrorHandler Tk_CreateErrorHandler(display, error, request, minor, proc, clientData) Tk_DeleteErrorHandler(handler)
typedef int Tk_ErrorProc(
ClientData clientData,
XErrorEvent *errEventPtr);
The clientData parameter to proc is a copy of the clientData
argument given to Tcl_CreateErrorHandler when the callback
was created. Typically, clientData points to a data
structure containing application-specific information that is
needed to deal with the error. ErrEventPtr is
a pointer to the X error event.
The procedure proc should return an integer value. If it
returns 0 it means that proc handled the error completely and there
is no need to take any other action for the error. If it returns
non-zero it means proc was unable to handle the error.
