<div><div class="section"><h4 class="sectiontitle">Purpose</h4> <p>Returns the message substitution data for
|
|
the top-level (the most recent) message identified by the error handle provided.
|
|
This message attribute only pertains to messages returned from the iSeries™ server.
|
|
The substitution data are inserted into the substitution variable fields defined
|
|
for the message. </p>

<dd>Pointer to a buffer that will receive the substitution data for the message

returned as an ASCIIZ string. Any character strings contained in the substitution

data are returned as EBCDIC values.</dd>

<dd>Optional, may be NULL. A return address to store the number of bytes needed

completion.</dd>

<div class="section"><h4 class="sectiontitle">Usage</h4> <p> iSeries server messages may be added
|
|
to the error handle when using the cwbRC_CallPgm() and cwbRC_RunCmd() API's.
|
|
In these cases, you can use this API to retrieve the substitution data for
|
|
the iSeries server
|
|
messages contained in the error handle. If there is no substitution data for
|
|
the message, return code CWBSV_ATTRIBUTE_NOT_SET will be returned. Use the
|
|
returnLength parameter to determine the actual number of bytes returned in
|
|
the substitution data when the return code is CWB_OK. The substitution data
|
|
returned on this API could be used on a subsequent host retrieve message API
|
|
call (QSYS/QMHRTVM) to retrieve the format of the substitution data or to
|
|
return secondary help text with the substitution data added in. Host API's
|
|
are called using the cwbRC_CallPgm() API.</p>
