NAME
       PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
       #include <pcre2.h>
       int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext,
         PCRE2_SIZE value);
DESCRIPTION
       This  function  sets, in a compile context, the maximum text length (in
       code units) of the pattern that can be compiled. The result  is  always
       zero.  If  a  longer  pattern  is passed to pcre2_compile() there is an
       immediate error return. The default is effectively unlimited, being the
       largest value a PCRE2_SIZE variable can hold.
       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.
