#include <pcre2.h>

pcre2_code *pcre2_code_copy_with_tables(const pcre2_code *code);


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.
