@c Some parts of the implementation open /proc and /sys files and dirs
@c to collect system details, using fd and stream I/O depending on the
@c case. _SC_TZNAME_MAX calls __tzname_max, that (while holding a lock)
@c calls tzset_internal, that calls getenv if it's called the first
@c time; there are free and strdup calls in there too. The returned max
@c value may change over time for TZNAME_MAX, depending on selected
@c timezones; NPROCS, NPROCS_CONF, PHYS_PAGES, AVPHYS_PAGES,
@c NGROUPS_MAX, SIGQUEUE_MAX, depending on variable values read from
@c /proc at each call, and from rlimit-obtained values CHILD_MAX,
@c OPEN_MAX, ARG_MAX, SIGQUEUE_MAX.
This function is used to inquire about runtime system parameters. The
@var{parameter} argument should be one of the @samp{_SC_} symbols listed
below.

This is just like @code{pathconf} except that an open file descriptor
