Hello.

SunOS 5.5.1 aka Solaris 2.5.1 returns EAGAIN.

glibc 2.1.3 on RedHat 6.2 has lockf() in its headers -
/usr/include/fcntl.h, /usr/include/unistd.h - but seemingly there's no
description of lockf() in the man pages of info docs.

Unix98 aka SUSv2 says that either EACCES or EAGAIN can be returned.

This is all according to the documentation. I have not done any Real Life
Tests, but I hope they conform to their docs.

Bye,
