I would like to ask a question about CURSES library programming-Linux general technology-Linux programming and kernel information. The following is a detailed description. You have encountered a problem in curses. h library programming and cannot solve it by yourself. Therefore, please ask experts for help.

The logic is as follows:
.......
Int ch = getch ();

If (ch = 27)
Exit (0 );
Else
........

My intention is to exit the program only after pressing the ESC key, but now the problem is:
I press ESC and another function key to exit.
The function key is set to "^ [3 ~ "
