A neat usage example would be: -# -# AX_HAVE_SELECT( -# [AX_CONFIG_FEATURE_ENABLE(select)], -# [AX_CONFIG_FEATURE_DISABLE(select)]) -# AX_CONFIG_FEATURE( -# [select], [This platform supports select(7)], -# [HAVE_SELECT], [This platform supports select(7).]) -# -# Some systems also have the variant pselect(). The availability of that -# function can be tested with the second macro. Generally speaking, it is -# safe to assume that AX_HAVE_SELECT would succeed if AX_HAVE_SELECT_PWAIT -# has, but not the other way round. -# -# LICENSE -# -# Copyright (c) 2009 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.
