# SYNOPSIS
#
# AX_HAVE_EPOLL([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
# AX_HAVE_EPOLL_PWAIT([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
# This macro determines whether the system supports the epoll I/O event
# interface. A neat usage example would be:
#
# AX_HAVE_EPOLL(
# [AX_CONFIG_FEATURE_ENABLE(epoll)],
# [AX_CONFIG_FEATURE_DISABLE(epoll)])
# AX_CONFIG_FEATURE(
# [epoll], [This platform supports epoll(7)],
# [HAVE_EPOLL], [This platform supports epoll(7).])
#
# The epoll interface was added to the Linux kernel in version 2.5.45, and
# the macro verifies that a kernel newer than this is installed. 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.
