getisax(2)                       System Calls                       getisax(2)

NAME
       getisax - extract valid instruction set extensions

SYNOPSIS
       #include <sys/auxv.h>

       uint_t getisax(uint32_t *array, uint_t n);

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


       Values for AV_xxx_yyy for SPARC and SPARCV9, and their  associated  de‐
       scriptions, can be found in <sys/auxv_SPARC.h>.


       Values for AV_xxx_yyy for i386 and AMD64, and their associated descrip‐
       tions, can be found in <sys/auxv_386.h>.


       If  n is zero and array is NULL, the number of array elements needed to
       hold all the non-zero values will be returned and array will not be ac‐
       cessed. The number returned can differ between  systems  and  releases,
       reflecting the number of extensions supported by each.

RETURN VALUES
       The  getisax()  function  returns  the maximum number of array elements
       that contain non-zero values. This may differ from the caller  supplied
       value of the n argument.

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



       In the following example, if the message is written, the SSE2  instruc‐
       tion set is present and fully supported by the operating system.


         uint_t n = getisax(NULL, 0);
         uint_t *ui = calloc(n, sizeof(uint_t));

         (void) getisax(ui, n);
         if (ui[AV_HW1_IDX] & AV_386_SSE2) {
             printf("SSE2 instruction set extension is present.\n");
         }

NOTES
       Instruction extensions to the native platform ABI are also  represented
       by  hardware capabilities. For a complete description of hardware capa‐
       bilities, refer to the Oracle Solaris 11.4 Linkers and Libraries Guide.

HISTORY
       The getisax() function was added in the Solaris 10 3/05 release.
