NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       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:

         errorcode   an error code (positive or negative)
         buffer      where to put the message
         bufflen     the length of the buffer (code units)

       The function returns the length of the message, excluding the trailing zero, or a negative
       error code if the buffer is too small.

       There is a complete description of the PCRE2  native  API  in  the  pcre2api  page  and  a
       description of the POSIX API in the pcre2posix page.
