- .TH PCRE2_JIT_COMPILE 3 "29 July 2019" "PCRE2 10.34"
- .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);
- .fi
- .
- .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
- .sp
- There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been
- superseded by the \fBpcre2_compile()\fP option PCRE2_MATCH_INVALID_UTF. The old
- option is deprecated and may be removed in the future.
- .P
- 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. The function can also return
- PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the
- compiler, even if it was because of a system security restriction.
- .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.
