I neither have the docs, experience nor time to be of any help save that I can try patches/compilations for you. I found these people in reference to libc_r whom could prove helpful or insightful for your endeavours: John Birrell <jb@freebsd.org> Peter Dufault <dufault@freebsd.org> Good luck. -- Jeroen Ruigrok van der Werven/Asmodai asmodai(at)wxs.nl The BSD Programmer's Documentation Project <http://home.wxs.nl/~asmodai>; Network/Security Specialist BSD: Technical excellence at its best Seek, and ye shall find; knock, and it shall be opened unto you.
