SYNOPSIS
 

#include &#60;pcre2.h&#62;


int pcre2_get_error_message(int errorcode, PCRE2_UCHAR *buffer,
 PCRE2_SIZE bufflen);

 
DESCRIPTION
 

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>
 errorcode an error code (positive or negative)
 buffer where to put the message
 bufflen the length of the buffer (code units)
</pre>
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 errorcode does not contain a recognized error code
number, the negative value PCRE2_ERROR_BADDATA is returned.
