Syntax

bool
JS_ExecuteRegExp(JSContext *cx, JS::HandleObject obj, JS::HandleObject reobj,
                 char16_t *chars, size_t length, size_t *indexp, bool test,
                 JS::MutableHandleValue rval);

bool
JS_ExecuteRegExpNoStatics(JSContext *cx, JS::HandleObject reobj,
                          char16_t *chars, size_t length,
                          size_t *indexp, bool test,
                          JS::MutableHandleValue rval);

Description

JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics execute the RegExp object, reobj, to the specified input string, chars, from *indexp index.

If test is false, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics store the match result array to *rval if matches, otherwise stores null to *rval. If test is true, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics store the boolean value true to *rval if matches, otherwise stores null to *rval.

JS_ExecuteRegExp updates the built-in RegExp object's properties.

If successful, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics returns true and stores the result to *rval, otherwise returns false and the value of *rval is undefined
