NAME         top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS         top


       #include <pcre2.h>

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

DESCRIPTION         top


       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.
