Description

The XGetErrorText() function returns a string to the user for an error. XESetErrorString() allows you to define a procedure to be called that should return a pointer to the error message. The following is an example.


(*proc)(display, code, codes, buffer, nbytes)
	Display *display;
	int code;
	XExtCodes *codes;
	char *buffer;
	int nbytes;

Your procedure is called with the error code for every error detected. You should copy nbytes of a null-terminated string containing the error message into buffer.
