.TH PCRE2_CODE_COPY 3 "22 November 2016" "PCRE2 10.23" .SH NAME PCRE2 - Perl-compatible regular expressions (revised API) .SH SYNOPSIS .rs .sp .B #include <pcre2.h> .PP .nf .B pcre2_code *pcre2_code_copy(const pcre2_code *\fIcode\fP); .fi . .SH DESCRIPTION .rs .sp 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 \fBpcre2_jit_compile()\fP, the copy can be used only for non-JIT matching. The pointer to the character tables is copied, not the tables themselves (see \fBpcre2_code_copy_with_tables()\fP). The yield of the function is NULL if \fIcode\fP is NULL or if sufficient memory cannot be obtained. .P There is a complete description of the PCRE2 native API in the .\" HREF \fBpcre2api\fP .\" page and a description of the POSIX API in the .\" HREF \fBpcre2posix\fP .\" page.
