K 10 svn:author V 7 wollman K 8 svn:date V 27 2002-09-21T02:08:32.000000Z K 7 svn:log V 722 Define constants for those POSIX options and option groups which are (or would be) implemented (or not) exclusively in user-land. A threads expert should check over the values I have set to make sure that they correctly reflect reality. Move all sysconf() keys here from as they are not implemented in the kernel. Add new keys from 1003.1-2001 final text. (Some additional keys are expected in TC1.) Add some protection against redundant declarations between and for some functions which XSI requires in the former and BSD traditionally declares in the latter. Restrict qualifiers and other changes from 1003.1-2001 have not been made to the functions prototyped here. (3 of 5) END
