That is set in the C Library headers which are considered constant when RTEMS is built. AFAIK you'd have to patch the header in the C Library when building the tools using the RSB to have a possible clean solution. Editing the installed header would be uncool. How many descriptors do you need? And will you be using select()? --joel > Best Regards > Mirek > _______________________________________________ > users mailing list > users@rtems.org > http://lists.rtems.org/mailman/listinfo/users
