  27 RETURN VALUES
  28        The getisax() function returns the number of array elements that

  32        Example 1 Use getisax() to determine if the SSE2 instruction set is
  33        present.

  36        In the following example, if the message is written, the SSE2
  37        instruction set is present and fully supportred by the operating
  38        system.
