|
|
<div><div class="section"><h4 class="sectiontitle">Purpose</h4>
|
|
<p>This function creates a message text object and returns a handle to it.
|
|
This message handle can be used in your program to write message text to the
|
|
currently active history log. The message text is supplied in a buffer passed
|
|
on the cwbSV_LogMessageText() call.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Syntax</h4>
|
|
<pre>
|
|
unsigned int CWB_ENTRY cwbSV_CreateMessageTextHandle(
|
|
char *productID,
|
|
char *componentID,
|
|
cwbSV_MessageTextHandle *messageTextHandle);</pre>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Parameters</h4>
|
|
<dl><dt class="dlterm">char * productID - input</dt>
|
|
<dd>Points to a null-terminated string that contains a product identifier
|
|
to be used on this message entry. Parameter is optional, if null, no productID
|
|
is set. NOTE: A maximum of CWBSV_MAX_PRODUCT_ID characters will be logged
|
|
for the product ID. Larger strings will be truncated.</dd>
|
|
<dt class="dlterm">char * componentID - input</dt>
|
|
<dd>Points to a null-terminated string that contains a component identifier
|
|
to be used on this message entry. Parameter is optional, if null, no componentID
|
|
is set. NOTE: A maximum of CWBSV_MAX_COMP_ID characters will be logged for
|
|
the component ID. Larger strings will be truncated.</dd>
|
|
<dt class="dlterm">cwbSV_MessageTextHandle * messageTextHandle - input/output</dt>
|
|
<dd>Pointer to a cwbSV_MessageTextHandle where the handle will be returned.
|
|
This handle should be used in subsequent calls to the message text functions.</dd>
|
|
</dl>

</div>
|
|
<div class="section"><h4 class="sectiontitle">Return Codes</h4>
|
|
<p>The following list shows common return values.</p>
|
|
|
|
<dl><dt class="dlterm">CWB_OK</dt>
|
|
<dd>Successful completion.</dd>
|
|
<dt class="dlterm">CWB_INVALID_POINTER</dt>
|
|
<dd>NULL passed on output parameter.</dd>
|
|
<dt class="dlterm">CWB_NOT_ENOUGH_MEMORY</dt>
|
|
<dd>Insufficient memory to create handle.</dd>

|
<div class="section"><h4 class="sectiontitle">Usage</h4>
|
|
<p>It is recommended that you set a unique product ID and component ID in
|
|
the message handle before using it to log message text. These ID's will distinguish
|
|
your messages from other messages in the history log.</p>
