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(3) page and a description of the POSIX API in the pcre2posix(3) page.
