Synopsis: sysconf() does not support well-defined unistd values State-Changed-From-To: open->analyzed State-Changed-By: rodrigc State-Changed-When: Fri Sep 2 17:53:02 GMT 2005 State-Changed-Why: Whether or not a constant is defined in <unistd.h> is not relevant to whether sysconf() accepts it or not (unfortunately). The list of constants supported by sysconf() are handled in /usr/src/lib/libc/gen/sysconf.c Any constant which is not handled there will return a -1, and set errno to EINVAL, which is legal behavior with respect to the Single Unix Specification. For _SC_GETGR_R_SIZE_MAX, it is difficult to return a single value, because in the file where this implemented ( /usr/src/lib/libc/gen/getgrgent.c ), the getgr*_r functions are delegated down to _nsdispatch(). http://www.freebsd.org/cgi/query-pr.cgi?pr=80293home | help
