PCRE2 - Perl-compatible regular expressions (revised API)

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. PCRE2 10.45 22 November 2016 PCRE2_CODE_COPY(3)
