Path Name: /hp-ux_patches/s700/10.X/PHKL_17592

Symptoms:
	PHKL_17592:
	Port of PHKL_8693 unmodified

	(PHKL_8693)
	The two visible symptoms are:
	   - The new ANSI/C++ compiler reports an error as it
	     is not getting the correct prototype for the
	     __fd_isset() fuction.
	   - enables backward compatibility for source code using
	     the old select() system call prototype:
	        extern int select(size_t, int *, int *, int *,
	           const struct timeval*);
	     The X/Open compliant prototype is now used by default:
	        extern int select(int, fd_set *, fd_set *, fd_set *,
	           struct timeval*);
	     Patch PHCO_8667 requires installation of this patch.
	     To use the old style select(), use "#include <time.h>"
	     instead of "#include <sys/time.h>", and be sure that
	     the flag _XOPEN_SOURCE_EXTENDED does not get defined
	     while compiling the application code.
	(PHKL_7962)
	The declaration of "extern struct sigevent;" in time.h
	is illegal in Ansi C++.

Defect Description:
	PHKL_17592:
	Port of 10.20 PHKL_8693

	(PHKL_8693)
	The two defects that are being corrected in this patch are:
	   - Since the __cplusplus flag was not being
	     checked for, the ANSI/C++ compiler was not
	     getting the ANSI prototype for the __fd_isset()
	     function definition. The only flag that was
	     being checked for was __STDC__, which is not
	     set by the ANSI/C++ compiler.
	   - Regarding the select() function prototype:
	     time.h and sys/time.h did not allow access to
	     the old non- X/Open compliant select() prototype
	     when _XPG4_EXTENDED was defined.

	Resolution:
	Port of 10.20 PHKL_8693

Installation Instructions:
	Please review all instructions and the Hewlett-Packard
	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,
	restrictions, and, limitation of liability and warranties,
	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHKL_17592

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHKL_17592.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHKL_17592.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHKL_17592.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHKL_17592.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHKL_17592.depot of=/dev/rmt/0m bs=2k
