NAME top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS top


       #include <pcre2.h>

       int pcre2_set_max_pattern_length(pcre2_compile_context *ccontext,
         PCRE2_SIZE value);

DESCRIPTION top


       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.
