Real sense of deja-vu here. Didn't we go through this same thing with
the HPI socket routines?
Yes, and the networking native code too.
I think it is best to use socklen_t for the unix code. From what I can
see making these changes, to use socklen_t, should be relatively localized.

Depending on the OS (and version?) we should be using socklen_t not int
and not uint32_t.

John,
I grabbed your patch, and with it I now see different warnings.

Do you see these in your build?

John - this is the debugger socket transport so cc'ing the
serviceability-dev list as that is where this code is maintained.

Greetings:
Please consider the following change to the two files:
src/share/transport/socket/sysSocket.h
src/solaris/transport/socket/socket_md.c
that eliminate compiler warnings that stem from the fact that the
variables that the native code passes to various system calls were not
declared correctly. They were declared as integers, but they must be
"unsigned" integers because they are used to define buffer lengths.
Were one to supply a negative value as an argument, it would be cast
into an unsigned "Martian" value and there'd be (hopefully) a system
call error.
Thanks!
