       PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       pcre2_code *pcre2_code_copy(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. The pointer to the character tables is copied, not the
       tables themselves (see pcre2_code_copy_with_tables()). 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.
