addssys Subroutine

Base Operating System and Extensions Technical Reference, Volume 1

addssys Subroutine

Purpose

Adds the SRCsubsys record to the subsystem object class.

Library

System Resource Controller Library (libsrc.a)

Syntax

#include <sys/srcobj.h>
#include <spc.h>

int addssys (SRCSubsystem )
struct SRCsubsys *SRCSubsystem;

Description

The addssys subroutine adds a record to the subsystem object class. You must call the defssys subroutine to initialize the SRCSubsystem buffer before your application program uses the SRCsubsys structure. The SRCsubsys structure is defined in the /usr/include/sys/srcobj.h file.

The executable running with this subroutine must be running with the group system.

Parameters

SRCSubsystem

A pointer to the SRCsubsys structure.

Return Values

Upon successful completion, the addssys subroutine returns a value of 0. Otherwise, it returns a value of -1 and the odmerrno variable is set to indicate the error, or an SRC error code is returned.

Error Codes

The addssys subroutine fails if one or more of the following are true:

SRC_BADFSIG	Invalid stop force signal.
SRC_BADNSIG	Invalid stop normal signal.
SRC_CMDARG2BIG	Command arguments too long.
SRC_GRPNAM2BIG	Group name too long.
SRC_NOCONTACT	Contact not signal, sockets, or message queue.
SRC_NONAME	No subsystem name specified.
SRC_NOPATH	No subsystem path specified.
SRC_PATH2BIG	Subsystem path too long.
SRC_STDERR2BIG	stderr path too long.
SRC_STDIN2BIG	stdin path too long.
SRC_STDOUT2BIG	stdout path too long.
SRC_SUBEXIST	New subsystem name already on file.
SRC_SUBSYS2BIG	Subsystem name too long.
SRC_SYNEXIST	New subsystem synonym name already on file.
SRC_SYN2BIG	Synonym name too long.

Auditing Events:

If the auditing subsystem has been properly configured and is enabled, the addssys subroutine generates the following audit record (event) each time the subroutine is executed:

Event	Information
SRC_addssys	Lists the SRCsubsys records added.

See "How to Set Up Auditing" in AIX Version 4.3 System Management Guide: Operating System and Devices for details about selecting and grouping audit events, and configuring audit event data collection.

Implementation Specifics

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

/etc/objrepos/SRCsubsys	SRC Subsystem Configuration object class.
/dev/SRC	Specifies the AF_UNIX socket file.
/dev/.SRC-unix	Specifies the location for temporary socket files.
/usr/include/spc.h	Defines external interfaces provided by the SRC subroutines.
/usr/include/sys/srcobj.h	Defines object structures used by the SRC.
