HP UX 11i v1 I/O Cards manual Return Param Response data

ZCOM C I/F Library Routines

ZCONFIG (3X)

node	Destination node.
	This is the node number of the remote (or local) ZCOM
	system where the configuration is to take place. If zero
	is specified, it is the local system. Note that the node
	parameter must specify the local system with this
	release (except for the Port Configuration functions)
cdata	Configuration data.
	This points to a data structure containing all the
	information necessary for the configuration. See below
	for a description of this structure.

rdata

(Return Param) Response data.

This points to a data structure containing the returned configuration response data. It is returned with valid data only when it is an immediate configuration (mode ZcDSC_IMMEDIATE) and zconfig returns with zero (i.e. no error). See the following for a description of this structure.

Configuration Data The configuration data structure consists of a header and a “union” data portion for configuration information

/* Configuration Header */
typedef struct {
uint16	config;	/* Type of configuration */
uint16	action;	/* Configuration action */
uint16	tag1;	/* Tag parameter 1 */
uint16	tag2;	/* Tag parameter 2 */
} zcfghdr_type;
/* Configuration Data */
typedef struct {
zcfghdr_type		header;	/* Header Information */
union {
struct {
	uint32	cfg_class;	/* Class of Reconfig (1-999 Resvd) */
	uint32	cfg_info1;	/* Caller supplied information. */
} setctl;			/* Request = DSC Control */
struct {
	char	sysname[80]; /* New ZCOM system name */
	uint32	qlimit;	/* Queue limit */
} setsys;
struct {
	uint16	iftno;	/* Interface card number */
