<H2>DESCRIPTION</H2>
|
|
|
|
|
|
<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:
|
|
<P>
|
|
<BR> <I>errorcode</I> an error code (positive or negative)
|
|
<BR> <I>buffer</I> where to put the message
|
|
<BR> <I>bufflen</I> the length of the buffer (code units)
|
|
<P>
|
|
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.
|
|
<P>
|
|
|
|
