问题
I can see from various documentations that XCloseDisplay
returns an integer, which I suspect to be an error code.
What should I do with this value? Is it an error code? If so how do I handle the error?
回答1:
I looked in the source code (lib/X11/ClDisplay.c
)
It says:
return 0;
So there's nothing you can really do with the return value.
