This is the first time I've ever used the POSIX config mechanisms, so I may have it wrong. I'll check... Hum... I find the POSIX docs for sysconf() pretty impeneratable regarding the return value. I can see why I took >=0 to be needed, but I could also read it in a way that >0 would be OK.
Any POSIX experts out there?
Finally, readdir_r() is available on FreeBSD even though neither _POSIX_THREAD_SAFE_FUNCTIONS not _SC_THREAD_SAFE_FUNCTIONS is defined. I don't know how to test for it though, FreeBSD's sysconf() only claims to support POSIX 1990, even though some later interfaces are available.
Someone with access to that system needs to figure out what PP macro to look for.
Once we get this figured out, I'd like to put this into the config library. I need this config info in date-time and it looks like the filesystem and time access functions normally use the same macro (at least for this platform). I'd suggest something like: BOOST_HAS_POSIX_THREAD_SAFE_FUNCTIONS No hurry -- we should wait until after 1.33 when there is less chance of perturbing the release ;-) Jeff
