.TH DLPI_GET_PHYSADDR 3DLPI "Aug 22, 2007"
.SH NAME
dlpi_get_physaddr \- get physical address using DLPI
.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-ldlpi\fR [ \fIlibrary\fR... ]
#include <libdlpi.h>
\fBint\fR \fBdlpi_get_physaddr\fR(\fBdlpi_handle_t\fR \fIdh\fR, \fBuint_t\fR \fItype\fR,
\fBvoid *\fR\fIaddrp\fR,\fBsize_t *\fR\fIaddrlenp\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBdlpi_get_physaddr()\fR function gets a physical address from the
\fBDLPI\fR link instance associated with \fBDLPI\fR handle \fIdh\fR. The
retrieved address depends upon \fItype\fR, which can be:
.sp
.ne 2
.na
\fB\fBDL_FACT_PHYS_ADDR\fR\fR
.ad
.RS 21n
Factory physical address
.RE
.sp
.ne 2
.na
\fB\fBDL_CURR_PHYS_ADDR\fR\fR
.ad
.RS 21n
Current physical address
.RE
.sp
.LP
The operation can be performed in any \fBDLPI\fR state of \fIdh\fR.
.sp
.LP
The caller must ensure that \fIaddrp\fR is at least \fBDLPI_PHYSADDR_MAX\fR
bytes in size and \fIaddrlenp\fR must contain the length of \fIaddrp\fR. Upon
success, \fIaddrp\fR contains the specified physical address, and
\fIaddrlenp\fR contains the physical address length. If a physical address is
not available, \fIaddrp\fR is not filled in and \fIaddrlenp\fR is set to zero.
.SH RETURN VALUES
.sp
.LP
Upon success, \fBDLPI_SUCCESS\fR is returned. If \fBDL_SYSERR\fR is returned,
\fBerrno\fR contains the specific UNIX system error value. Otherwise, a
\fBDLPI\fR error value defined in \fB<sys/dlpi.h>\fR or an error value listed
in the following section is returned.
.SH ERRORS
