PCRE2_JIT_COMPILE(3) FreeBSD Library Functions Manual PCRE2_JIT_COMPILE(3)
NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
int pcre2_jit_compile(pcre2_code *code, uint32_t options);
DESCRIPTION
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 pcre2_match()
interpretive matching function. Full details are given in the pcre2jit
documentation.
The first argument is a pointer that was returned by a successful call
to pcre2_compile(), and the second must contain one or more of the
following bits:
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
There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which
has been superseded by the pcre2_compile() option
PCRE2_MATCH_INVALID_UTF. The old option is deprecated and may be
removed in the future.
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 options. 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.
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.
