Hello, I have been looking for a macro that will allow me to test to see if a structure exists in a header, and if it has a particular member. I'm writing things that depend on external libraries that are still 'moving targets'. For instance, if a library exposes struct foo { , I need to see if foo has a member named bar. I've been looking around for a day or two, but can't seem to locate a generic macro that would be suitable... or I'm just flat out missing it in the autoconf manual. This could be the case, I think I've gone a little snow blind while looking. I wanted to ask this list prior to trying to write one myself. Thanks in advance for any replies :) Cheers, --Tim _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
