System Calls                                           getisax(2)



NAME
     getisax - extract valid instruction set extensions

SYNOPSIS
     #include 

     uintt getisax(uint32t *array, uintt n);


DESCRIPTION
     The getisax() function sets the vector  array  of  n  32-bit
     integers  to  contain the bits from the AVxxxyyy namespace
     of the given instruction set architecture.


     Values for AVxxxyyy for SPARC and SPARCV9, and their asso-
     ciated descriptions, can be found in .


     Values for AVxxxyyy for i386 and AMD64, and their  associ-
     ated descriptions, can be found in .

RETURN VALUES
     The getisax() function returns the number of array  elements
     that contain non-zero values.

EXAMPLES
     Example 1 Use getisax() to determine if the SE2 instruction
     set is present.


     In the following example, if the  message  is  written,  the
     SE2  instruction set is present and fully supportred by the
     operating system.


       uintt ui;

       (void) getisax(&ui, 1);

       if (ui & AV386SE2)
               printf("SE2 instruction set extension is present.\n");
