NAME top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS top


       #include <pcre2.h>

       pcre2_code *pcre2_code_copy_with_tables(const pcre2_code *code);

DESCRIPTION top


       This function makes a copy of the memory used for a compiled
       pattern, excluding any memory used by the JIT compiler. Without a
       subsequent call to pcre2_jit_compile(), the copy can be used only
       for non-JIT matching.  Unlike pcre2_code_copy(), a separate copy
       of the character tables is also made, with the new code pointing
       to it. This memory will be automatically freed when
       pcre2_code_free() is called. The yield of the function is NULL if
       code is NULL or if sufficient memory cannot be obtained.

       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.
