ZCONFIG (3X)

NAME zconfig – ZCOM Dynamic System Configuration (DSC)

SYNOPSIS

#include <zcom/zcomsys.h>

#include <zcom/zcomcall.h> /* If compliled with ANSI C (recommended) */

int32 zconfig (zap, mode, node, cdata, rdata)

zaddr_type *zap;

uint32 mode;

uint32 node;

zconfig_type *cdata;

zcfgret_type *rdata;

DESCRIPTION Routine zconfig provides a general purpose mechanism for configuring a

ZCOM system dynamically, i.e. altering some of the system tables or

hardware settings while the system is running.

ATTENTION: The current release provides very limited user support

for the functionality documented here. Specifically, the only supported

functions are the Dynamic System Configuration (DSC) Control request

to send a “Reconfiguration Complete” system event message and all of

the Port Configuration actions.

The configuration modified by use of the zconfig routine is only effective

while this instance of the ZCOM subsystem is running. The new

configuration remains in force until changed by another call or until the

ZCOM system is reinitialized. If the ZCOM subsystem is shutdown and

restarted, the original configuration defined in the TTGEN configuration

file is restored and all dynamic configuration changes are lost. Therefore,

all permanent configuration information should be defined in the

TTGEN configuration file.

This routine is intended for use by advanced user programs and should

be used with care. Since this routine is used to dynamically modify the

internal data structures used in the ZCOM subsystem, applications

which use this functionality may need to be recompiled with new

releases of the ACC base product.

The libraries libzcom_c.a and libpthread.a must be linked into the calling

program by giving the options “-lzcom_c -lpthread” to cc(1) or ld(1)
