how many file descriptors?

[Mike Khaw]

How can a SunView program tell how many file descriptors it has in use,
especially if it opens&closes /dev/fb several times and creates&destroys
frames several times while it's running?

I have a SunView program that uses many frames and I want to be able to
check that I won't exceed my per-process file descriptor limit (30 in
SunOS 3.x) before creating a new frame.

Thanks,
Mike Khaw
