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 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.

       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.
