c output doesn't show up through JNI?

[Kay]

Hi, all:

The standard outputs(screen output) from the c libraray I am using usually
don't show up or show up very late. I guess it's related to how the c
library outputs to the standard device, maybe they used buffered stream or
something. But it's not my code so I cannot change it. Is there anything I
can do at the Java side to force the c output to show up?

thanks,
