fflush problem

[qbps2]

Hello,
Thank you first! Your log macro is very good!
But when I used your sample code, I found the log message sometimes delay.
I add the code fflush(stderr);. this phenomenon will dismiss.
If I would like to add fflush(stderr) int the log macro, how do I do it?

do you have a newline character \n after you message?
