Signature
native Regex:regex_compile_ex(const pattern[], flags = 0, error[] = "", maxLen = 0, &errcode = 0);
Description
Precompile a regular expression.
Notes
-
Use this if you intend on using the same expression multiple times.
Pass the regex handle returned here to regex_match_c() to check for matches.
- Unlike regex_compile(), this allows you to use PCRE flags directly.
Parameters
- pattern — The regular expression pattern.
- flags — General flags for the regular expression, see PCRE_* defines.
- error — Error message encountered, if applicable.
- maxLen — Maximum string length of the error buffer.
- errcode — Regex type error code encountered, if applicable. See REGEX_ERROR_* defines.
Returns
Valid regex handle (> 0) on success, or -1 on failure.
