請教各位網友,
自己目前在寫的Xwindow的程式,
但執行到一半會當掉,
終端機有出現錯誤訊息如下:
The program 'a.out' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 7 error_code 3 request_code 20 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

請問其中的error_code我要查何份文件呢?
而serial, request_code, 與minor_code又是什麼意思呢？
謝謝。
