I've been looking into this, but -1 seems to be the correct way for the implementation to report that it does not impose an arbitrary limit. The specification of limits.h calls for these macros to be defined with "minimum maximum" values (the lowest limit the implementation might impose) while sysconf may return a more-relaxed value. It's not 100% clear whether it's intended that sysconf return -1 for them, but it seems valid and reasonable. I'd like to hear other opinions on the matter. Rich
