SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int pcre2_get_error_message(int <i>errorcode</i>, PCRE2_UCHAR *<i>buffer</i>,</b>
<b> PCRE2_SIZE <i>bufflen</i>);</b>
</P>
<br><b>
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 17:53:38 +01:00
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.
