PCRE2\_CODE\_COPY(3) Library Functions Manual PCRE2\_CODE\_COPY(3)

# [NAME](#NAME)

PCRE2 - Perl-compatible regular expressions (revised API)

# [SYNOPSIS](#SYNOPSIS)

**#include <pcre2.h>**

```
pcre2_code *pcre2_code_copy(const pcre2_code *code);
```

# [DESCRIPTION](#DESCRIPTION)

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.
