I guess this goes some way to answering a question I posed previously and got no response to - POSIX threading is essentially not supported in FreeBSD (yet). Some time ago I remember John Dyson and others discussing adding what I would consider to be a good level of threading support with the kernel handling most issues and providing signals or calls up to libc so that a M:N system would be viable, somewhat like Solaris or Digital UNIX. Previously I was told to 'read the man pages' but could find little evidence of any support for threading or AIO - and in particular sysconf doesn't look much like my copy of 1003.1(1996) would lead me to expect. Is anyone working on support for POSIX synchronization objects and threads? Ideally, with the optional inter-process support (hence, I was encouraged by the prospect of a thrad-savvy kernel rather than a fake in libc_r and userland) What's the state of play? Is there somewhere on FreeBSD.ORG that lists which of the portability constants specified in 2.9.3 are actually provided (whether in unistd.h or not)? Is there a statement of which P1003.1(1996) facilities are provided, or a statement of intent? One of the things I like about FreeBSD is that it does appear to be 'managed' and I would have hoped that such statements would be feasible. Somneone care to put me right?
