|
|
<div><p>This topic identifies considerations when specifying an exit program.</p>
|
|
<p>When you specify an exit program the servers pass the following
|
|
two parameters to the exit program before running your request:</p>
|
|
<ul><li>A 1-byte return code value</li>
|
|
<li>A structure containing information about your request (This structure
|
|
is different for each of the exit points.)</li>
|
|
</ul>
|
|
<p>These two parameters allow the exit program to determine whether your request
|
|
is possible. If the exit program sets the return code to X'F1', the server
|
|
allows the request. If the return code is set to X'F0' the server rejects
|
|
the request. If values other than X'F1' or X'F0' are set, the results will
|
|
vary depending upon which server is being accessed.</p>
|
|
<p>For multiple servers and exit points, the same program is usable. The program
|
|
can determine which server is being called and which function is being used
|
|
by looking at the data in the second parameter structure.</p>
|
|
<p>Exit program parameters documents the structures of the second parameter
|
|
that is sent to the exit programs. You can use this information to write your
|
|
own exit programs.</p>
