Revision: 3228 Author: eliot Date: 2015-01-13 10:10:05 -0800 (Tue, 13 Jan 2015) Log Message: ----------- Add a processor-agnostic include file for alien callouts and callbacks. Needed for linux where host_cpu and build_cpu are not necessarily the target cpu. Add some support for identifying the presence of epoll_wait & epoll_pwait on linux.

This +# check is somewhat unreliable if <linux/version.h> doesn't match the +# running kernel, but it is necessary regardless, because glibc comes with +# stubs for the epoll_create(), epoll_wait(), etc. that allow programs to +# compile and link even if the kernel is too old; the problem would then +# be detected only at runtime. +# +# Linux kernel version 2.6.19 adds the epoll_pwait() call in addition to +# epoll_wait(). The availability of that function can be tested with the +# second macro. Generally speaking, it is safe to assume that +# AX_HAVE_EPOLL would succeed if AX_HAVE_EPOLL_PWAIT has, but not the +# other way round. +# +# LICENSE +# +# Copyright (c) 2008 Peter Simons simons@cryp.to +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
