Has anyone run into problems with the bind() call on the SUN 386i?  I have
a program which runs fine on a SUN 4 under 4.0.1 but fails on the 386i
under 4.0.1. I create an internet stream socket successfully, but then the
subsequent bind call fails with an error return of EADDRNOTAVAIL. Any
ideas as to what I might be doing wrong?

The offending section of code is attached below.

[[ You need to "bzero(&name, sizeof(name));" before using it!  If it
worked on a Sun 4 then it was luck.  --wnl ]]
