The sysctl function from sys/sysctl.h seems to be used.  Usage may vary
between operating systems, there is a comment pertaining to FreeBSD:

    ~/tmp/coreutils$ fgrep -r sysctl .
    ./src/uname.c:# include <sys/sysctl.h>
    ./src/uname.c:          if (sysctl (mib, 2, processor, &s, 0, 0) >= 0)
    ./src/uname.c:              if (sysctlbyname ("hw.cputype", &cputype, &cs, 
NULL, 0) == 0
    ./src/uname.c:          if (sysctl (mib, 2, hardware_platform, &s, 0, 0) >= 
0)
    ./src/uptime.c:# include <sys/sysctl.h>
    ./src/uptime.c:    /* FreeBSD specific: fetch sysctl "kern.boottime".  */
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ./src/uptime.c:    if (sysctl (request, 2, &result, &result_len, NULL, 0) 
>= 0)
    ./tests/tail-2/inotify-rotate-resources.sh:    #  sudo sysctl -w 
fs.inotify.max_user_watches=$smallish_number
    ./m4/boottime.m4:  AC_CHECK_FUNCS([sysctl])
    ./m4/boottime.m4:  AC_CHECK_HEADERS([sys/sysctl.h], [], [],
    ./m4/boottime.m4:# include <sys/sysctl.h>
    ./m4/jm-macros.m4:    sysctl
    ./m4/jm-macros.m4:  AC_CHECK_HEADERS([sys/sysctl.h], [], [],
