BSD job control

[Roger Cornelius]

I'm attempting to port a program which uses BSD job control for use
with POSIX job control under system 5.  Can someone explain to me what
the BSD function sigsetmask() does.  I would also like to know what
the TIOCLGET and TIOCLSET ioctl() requests do.

Are BSD manuals available to non-BSD sites, and if so, from where?

Thanks.
