DL_PHYS_ADDR_ACK Primitive

Purpose

Returns the value for the physical address to the data link service (DLS) user in response to a DL_PHYS_ADDR_REQ primitive.

The message consists of one M_PCPROTO message block, which contains the following structure:
typedef struct { ulong dl_primitive; ulong dl_addr_length; ulong dl_addr_offset; } dl_phys_addr_req_t;

This structure is defined in /usr/include/sys/dlpi.h.

Description

The DL_PHYS_ADDR_ACK primitive returns the value for the physical address to the DLS user in response to a DL_PHYS_ADDR_REQ primitive.

Parameters

dl_primitive	Specifies the DL_ PHYS_ADDR_ACK primitive.
dl_addr_length	Specifies the length of the physical address.
dl_addr_offset	Indicates where the physical address begins. The value of this parameter is the offset from the beginning of the M_PCPROTO block.

States

Valid	The primitive is valid in any state in response to a DL_PHYS_ADDR_REQ primitive.
New	The resulting state is unchanged.

Implementation Specifics

This primitive is part of Base Operating System (BOS) Runtime.
