  18 .sp
  19 .LP
  20 The \fBgetisax()\fR function sets the vector \fIarray\fR of \fIn\fR 32-bit
  21 integers to contain the bits from the \fBAV\fR_\fIxxx\fR_\fIyyy\fR namespace of
  22 the given instruction set architecture.
  23 .sp
  24 .LP
  25 Values for \fBAV\fR_\fIxxx\fR_\fIyyy\fR for SPARC and SPARCV9, and their
  26 associated descriptions, can be found in \fB<sys/auxv_SPARC.h>\fR.
  27 .sp
  28 .LP
  29 Values for \fBAV\fR_\fIxxx\fR_\fIyyy\fR for i386 and AMD64, and their
  30 associated descriptions, can be found in \fB<sys/auxv_386.h>\fR.
  31 .SH RETURN VALUES
  32 .sp
  33 .LP
  34 The \fBgetisax()\fR function returns the number of array elements that contain
  35 non-zero values.
  36 .SH EXAMPLES

  38 \fBExample 1 \fRUse \fBgetisax()\fR to determine if the SSE2 instruction set is
  39 present.
