<h1 class="topictitle1">Error code parameter format</h1>
|
||
|
|
<div><p>Most iSeries™ APIs
|
||
|
|
include an error code parameter to return error codes and exception data to
|
||
|
|
the application. The error code parameter can be one of two variable-length
|
||
|
|
structures, format ERRC0100 or format ERRC0200.</p>
|
||
|
|
<div class="section"><p>In format ERRC0100, one field in that structure is an INPUT field;
|
||
|
|
it controls whether an exception is returned to the application or the error
|
||
|
|
code structure is filled in with the exception information. When the bytes
|
||
|
|
provided field is greater than or equal to 8, the rest of the error code structure
|
||
|
|
is filled in with the OUTPUT exception information associated with the error.
|
||
|
|
When the bytes provided INPUT field is zero, all other fields are ignored
|
||
|
|
and an exception is returned.</p>
|
||
|
|
<p>Format ERRC0200 must be used if the API
|
||
|
|
caller wants convertible character (CCHAR) support. Format ERRC0200 contains
|
||
|
|
two INPUT fields. The first field, called the key field, must contain a -1
|
||
|
|
to use CCHAR support. When the bytes provided field is greater than or equal
|
||
|
|
to 12, the rest of the error code structure is filled in with the OUTPUT exception
|
||
|
|
information associated with the error. When the bytes provided INPUT field
|
||
|
|
is zero, all other fields are ignored and an exception is returned.</p>
|
||
|
|
<p>For
|
||
|
|
some APIs, the error code parameter is optional. If you do not code the optional
|
||
|
|
error code parameter, the API returns diagnostic and escape messages. If you
|
||
|
|
do code the optional error code parameter, the API returns only escape messages
|
||
|
|
or error codes; it never returns diagnostic messages.</p>
|
||
|
|
<p>The structure
|
||
|
|
of the error code parameter is as follows. The fields are described in detail
|
||
|
|
after the tables.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> The error code structures for both formats are
|
||
|
|
provided in the QUSEC include file in the QSYSINC library. Includes exist
|

in the following source physical files: QRPGSRC, QRPGLESRC, QLBLSRC, QCBLLESRC,
