[ENet-discuss] [CMake] Autotools replacement functions?

[Andrew Fenn]

Thanks, this was really helpful. I am now just stuck on this function..

AC_EGREP_HEADER(MSG_MAXIOVLEN, socket.h,
AC_DEFINE(ENET_BUFFER_MAXIMUM, [MSG_MAXIOVLEN]))

I need something to search through an include file "socket.h", find
MSG_MAXIOVLEN and return true or false.

I've been searching but I couldn't find anything.

Regards,
Andrew
