Greetings all,

I'm wanting to include support for AIX for enqueue/dequeue and wait/notify features to be added to MCE::Shared for the upcoming 1.7 release. The optional features require the shared process to pass file handles (mutex fd's) to workers. The mutex handles are enabled on-demand. The reason is that not all shares require enqueue/dequeue or wait/notify capability.

This link suggest sendmsg/recvmsg compatibility between AIX and Linux. Thus, doing sendmsg/recvmsg in pure-Perl is possible on Linux, BSD/Darwin/DragonFly, including AIX. I'm missing the actual values from an AIX box.

Can a monk with access to an AIX box run the 3 liners please?

require 'sys/syscall.ph';      # this is built with h2ph
print "SYS_sendmsg: ", SYS_sendmsg(), "\n";
print "SYS_recvmsg: ", SYS_recvmsg(), "\n";

[download]

Building syscall.ph is typically done with one of the following:

( cd /usr/include; h2ph * sys/* )    or
( cd /usr/include; h2ph -r -l . )

[download]

But that requires root access. One can run as non-root with the -d option (destination). It has been a while and forgotten where the include files are located on AIX.

A likely fallback plan is IO::FDPass. It requires C and not sure if the module works on AIX. This module has one dependency which is Canary::Stability.

Thank you in advance for your time.

Sincerely, Mario
