Oracle's own documentation about rpcgen states that it has an -A flag which turns on MT auto mode in the generated code.
But on Ubuntu 16.04 LTS, rpcgen does not appear to have this option.
Does anybody know where to find a version for Linux which has this?
The preface page says the following
The Solaris 9 release is the Sun Microsystems distributed computing
operating environment. It includes SunOS release 5.9 with the ONC+
technologies and the Common Desktop Environment (CDE), as well as other
utilities.
I'm going to guess the feature I'm looking for is probably only available in SunOS 5.9.
Fortunately rpcgen comes with the -M option on Ubuntu, which generates thread-safe stubs. This still seems a step short of what I think the -A flag does though.
I'm not going to accept my own answer yet; hopefully I'm wrong.
