A text message for an error code from any PCRE2 function (compile, match, or
auxiliary) can be obtained by calling \fBpcre2_get_error_message()\fP. The code
is passed as the first argument, with the remaining two arguments specifying a
-code unit buffer and its length, into which the text message is placed. Note
-that the message is returned in code units of the appropriate width for the
