PCRE2_JIT_COMPILE(3) 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 com- piler 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 documenta- tion. The availability of JIT support can be tested by calling pcre2_com- pile_jit() with a single option PCRE2_JIT_TEST_ALLOC (the code argument is ignored, so a NULL value is accepted). Such a call returns zero if JIT is available and has a working allocator. Otherwise it returns PCRE2_ERROR_NOMEMORY if JIT is available but cannot allocate executable memory, or PCRE2_ERROR_JIT_UNSUPPORTED if JIT support is not compiled. Otherwise, the first argument must be 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compile code for hard partial matching There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been superseded by the pcre2_compile() option PCRE2_MATCH_IN- VALID_UTF. The old option is deprecated and may be removed in the fu- ture. The yield of the function when called with any of the three options above is 0 for success, or a negative error code otherwise. In particu- lar, 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. In a few cases, the function may return with PCRE2_ERROR_JIT_UNSUP- PORTED for unsupported features. 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. PCRE2 10.45 22 August 2024 PCRE2_JIT_COMPILE(3)
