NAME top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS top


       #include <pcre2.h>

       int pcre2_set_max_pattern_compiled_length(
         pcre2_compile_context *ccontext, PCRE2_SIZE value);

DESCRIPTION top


       This function sets, in a compile context, the maximum size (in
       bytes) for the memory needed to hold the compiled version of a
       pattern that is using this context. The result is always zero. If
       a pattern that is passed to pcre2_compile() referencing this
       context needs more memory, an error is generated. The default is
       the largest number that a PCRE2_SIZE variable can hold, which is
       effectively unlimited.

       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.
