       If this function returns -1 to indicate an error, the global variable will be set to one of the following values,  to  indicate	the  error
       that occurred:

	      The specified tunable parameter does not exist.

	      The Kernel Registry Service was unavailable or encountered an error.

	      tunable	   or value specifies an address that is inaccessible.

WARNINGS

       Some tunables have signed integer values.  For these tunables, the caller must cast the returned value to an type before using it.  To find
       out which tunables have signed integer values, use the tuneinfo2(2) system call, or consult the tunable parameter man pages.
