DESCRIPTION

|
</b><br>
|
|
|
|
|
<P>
|
|
|
|
|
This function provides a textual error message for each PCRE2 error code.
|
|
|
|
|
Compilation errors are positive numbers; UTF formatting errors and matching
|
|
|
|
|
errors are negative numbers. The arguments are:
|
|
|
|
|
<pre>
|
|
|
|
|
<i>errorcode</i> an error code (positive or negative)
|
|
|
|
|
<i>buffer</i> where to put the message
|
|
|
|
|
<i>bufflen</i> the length of the buffer (code units)
|
|
|
|
|
</pre>
|
2017-03-24 12:53:38 -04:00
|
|
|
The function returns the length of the message in code units, excluding the
|
|
|
|
|
trailing zero, or the negative error code PCRE2_ERROR_NOMEMORY if the buffer is
|
|
|
|
|
too small. In this case, the returned message is truncated (but still with a
|
|
|
|
|
trailing zero). If <i>errorcode</i> does not contain a recognized error code
|
|
|
|
|
number, the negative value PCRE2_ERROR_BADDATA is returned.
