I want to add this function to the aclocal.m4

How do I do it.

This should check for function prototypes.

Thanks

Chip

AC_DEFUN(AC_CHECK_FUNC_PROTO,
	[AC_CACHE_CHECK(for $1 function prototype in $2, ac_cv_have_$1_proto,
		AC_EGREP_HEADER($1, $2,
			ac_cv_have_$1_proto=yes,
			ac_cv_have_$1_proto=no))
	if test $ac_cv_have_$1_proto = yes ; then
    		ac_tr_func=HAVE_`echo $1 | tr 'abcdefghijklmnopqrstuvwxyz' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'`_PROTO
		AC_DEFINE_UNQUOTED($ac_tr_func)
	fi
])

the configure.ac has

AC_CHECK_FUNC_PROTO(gethostname, unistd.h)
AC_CHECK_FUNC_PROTO(getrusage, sys/resource.h)
AC_CHECK_FUNC_PROTO(isfdtype, sys/stat.h)
AC_CHECK_FUNC_PROTO(pselect, sys/select.h)
AC_CHECK_FUNC_PROTO(shm_open, sys/mman.h)

Thanks
