IBM Version 4 manual Problem Management APIs, Filtering

Ÿ	Twinaxial			ASCII	printing
Ÿ	LAN	ASCII		printing
Ÿ	TCP/IP		printing		through the Send	TCP/IP Spooled File command (known as
	LPR	or	line printer requester			in UNIX TCP/IP)

The API provides a programming interface to the same transform.

The QWPZHPTR API goes along with another					function, the Print Driver exit
program. This	exit program allows		you	to	create your own print driver p
For example, the system provides a print					driver to communicate to LAN-att
printers through the LexLink		protocol. This			print driver uses the host p
to convert the SNA-character-string spooled					files	or	AFP	spooled files		to
before sending them to the		printer.
With the QWPZHPTR API, you		can	write	your own		print		driver	(maybe	to
cate over a protocol other		than LexLink),			but	still	use the		system-provi
(host print	transform).

Spooled File		APIs
Spooled	file		APIs	obtain specific	information	about	spooled	files. For e
spooled file			APIs	can:
Ÿ Return		a	list	of spooled files	based on	given	selection	criteria,
or	an	output queue.

ŸProvide functions to access a specific spooled file from which the return the attributes and data of a spooled file or create a d spooled file.

Spooled file APIs are useful in writing applications to clean up, save, spooled files.

Problem Management APIs

The problem management APIs offer you the ability to write problem mana solutions, improve serviceability, and manage your own applications. Problem management APIs deal directly with how the AS/400 handles problems today. Today, the problem log provides most of the operations necessary for management in a network environment. These APIs have several capabilities:

Filtering

A filter	categorizes problem	log entries		into	groups and	performs operatio
them	accordingly.
The problem log applies the		currently	active		filter to	a problem log	e
problem entry is created,		changed,	or	deleted using		system-provided	in

The operations supported allow	you	to send	application notification to a
queue and assign the problem	to a user. Your application can receive
cations from the data queue	using	existing	APIs.
