This string will be empty if no FPU is attached. .sp .LP The \fBpi_clock\fR member is the processor clock frequency rounded to the nearest megahertz. It may be \fB0\fR if not known. .SH RETURN VALUES .sp .LP Upon successful completion, \fB0\fR is returned. Otherwise, \fB\(mi1\fR is returned and \fBerrno\fR is set to indicate the error. .SH ERRORS .sp .LP The \fBprocessor_info()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBEINVAL\fR\fR .ad .RS 10n .rt An non-existent processor \fBID\fR was specified. .sp The caller is in a non-global zone, the pools facility is active, and the processor is not a member of the zone's pool's processor set. .RE .sp .ne 2 .mk .na \fB\fBEFAULT\fR\fR .ad .RS 10n .rt The \fBprocessor_info_t\fR structure pointed to by \fIinfop\fR was not writable by the user. .RE .SH SEE ALSO .sp .LP \fBp_online\fR(2), \fBsysconf\fR(3C), \fBpooladm\fR(8), \fBpsradm\fR(8), \fBpsrinfo\fR(8), \fBzoneadm\fR(8)
