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.
