 * Commands to sysinfo(2)

 *    1 -  256	Unix International assigned numbers for `get' style commands.
 *  257 -  512	Unix International assigned numbers for `set' style commands
 *		where the value is selected to be the value for the
 *		corresponding `get' command plus 256.
 *  513 -  768	illumos-defined `get' style commands.
 *  769 - 1024	illumos-defined `set' style commands where the value is
 *		selected to be the value for the corresponding `get' command
 *		plus 256.
 *
 * These values have be registered
 * with Unix International can't be corrected now.  The status of a command
 * as published or unpublished does not alter the algorithm.
