<h1 class="topictitle1">Exit programs</h1>
|
||
|
|
<div><p>Exit programs are called and given control by an application program
|
||
|
|
or system program. They can be used to customize particular functions to your
|
||
|
|
needs. An <em>exit program</em> is a program to which control is passed from
|
||
|
|
a calling program.</p>
|
||
|
|
<p>Exit programs are usually user-written programs; however, a few are system-supplied
|
||
|
|
(such as a few of the Operational Assistant exit programs).</p>
|
||
|
|
<p>To transfer control to an exit program, you do an external call as you
|
||
|
|
would to any other program.</p>
|
||
|
|
<p>There are no general requirements for using exit programs. For any specific
|
||
|
|
requirements, see the documentation for the specific exit program.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Exit points</h4><p>An <em>exit point</em> signifies the point
|
||
|
|
in a system function or program where control is turned over to one or more
|
||
|
|
exit programs to perform a function.</p>
|
||
|
|
<p>Prior to Version 3 Release 1, the
|
||
|
|
exit program might have been represented as network attributes, system values,
|
||
|
|
CL command parameters, or attributes of system objects. Also, in previous
|
||
|
|
releases, all exit point providers had to supply their own means of registering
|
||
|
|
and deregistering exit programs.</p>
|
||
|
|
<p>The <em>registration facility</em> provides
|
||
|
|
a central point to store and retrieve information about <span class="keyword">i5/OS™</span> and
|
||
|
|
non-<span class="keyword">i5/OS</span> exit
|
||
|
|
points and their associated exit programs. This information is stored in the
|
||
|
|
registration facility repository and can be retrieved to determine which exit
|
||
|
|
points and exit programs already exist.</p>
|
||
|
|
<p>You can use the registration
|
||
|
|
facility APIs to register and deregister exit points, to add and remove exit
|
||
|
|
programs, and to retrieve information about exit points and exit programs.
|
||
|
|
You can also perform some of these functions by using the Work with Registration
|
||
|
|
Information (WRKREGINF) command.</p>
|
||
|
|
<p>The <em>exit point provider</em> is responsible
|
||
|
|
for defining the exit point information, defining the format in which the
|
||
|
|
exit program receives data, and calling the exit program.</p>
