|
|
.SH NAME
|
|
PCRE2 - Perl-compatible regular expressions (revised API)
|
|
.SH SYNOPSIS
|
|
.rs
|
|
.sp
|
|
.B #include <pcre2.h>
|
|
.PP
|
|
.nf
|
|
.B int pcre2_jit_compile(pcre2_code *\fIcode\fP, uint32_t \fIoptions\fP);

|
.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
This function requests JIT compilation, which, if the just-in-time compiler is
|
|
available, further processes a compiled pattern into machine code that executes
|
|
much faster than the \fBpcre2_match()\fP interpretive matching function. Full
|
|
details are given in the
|
|
.\" HREF
|
|
\fBpcre2jit\fP
|
|
.\"
|
|
documentation.
|
|
.P
|
|
The first argument is a pointer that was returned by a successful call to
|
|
\fBpcre2_compile()\fP, and the second must contain one or more of the following
|
|
bits:
|
|
.sp
|
|
PCRE2_JIT_COMPLETE compile code for full matching
|
|
PCRE2_JIT_PARTIAL_SOFT compile code for soft partial matching
|
|
PCRE2_JIT_PARTIAL_HARD compile code for hard partial matching
|
|
PCRE2_JIT_INVALID_UTF compile code to handle invalid UTF
|
|
.sp
|
|
The yield of the function is 0 for success, or a negative error code otherwise.
|
|
In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or
|
|
if an unknown bit is set in \fIoptions\fP.
|
