NAMEPCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS\.sp #include <pcre2.h> int pcre2_jit_compile(pcre2_code *code, uint32_t options);
DESCRIPTION\.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 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compile code for hard partial matching There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been superseded by the pcre2_compile() option PCRE2_MATCH_INVALID_UTF.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. 0
