  20   19  The \fBgetisax()\fR function sets the vector \fIarray\fR of \fIn\fR 32-bit
  21   20  integers to contain the bits from the \fBAV\fR_\fIxxx\fR_\fIyyy\fR namespace of
  22   21  the given instruction set architecture.
  23   22  .sp
  24   23  .LP
  25   24  Values for \fBAV\fR_\fIxxx\fR_\fIyyy\fR for SPARC and SPARCV9, and their
  26   25  associated descriptions, can be found in \fB<sys/auxv_SPARC.h>\fR.
