dmp_prinit Kernel Service

Purpose

Initializes the remote dump protocol.

Syntax

#include <sys/types.h>
#include <sys/errno.h>
#include <sys/dump.h>

void dmp_prinit ( dmp_proto, proto_info) int dmp_proto; void *proto_info;

Parameters

dmp_proto	Identifies the protocol. The values for the dmp_proto parameter are defined in the /usr/include/sys/dump.h file.
proto_info	Points to a protocol-specific structure containing information required by the system dump services. For the TCP/IP protocol, the proto_info parameter contains a pointer to the ARP table.

Description

When a communications subsystem is configured, it makes itself known to the system dump services by calling the dmp_prinit kernel service. The dmp_prinit kernel service identifies the protocol and passes protocol-specific information, which is required for a remote dump.

Execution Environment

The dmp_prinit kernel service can be called from the process environment only.
