                         unsigned indent);
    
    Name Type Description
    cx JSContext * Pointer to a JS context from which to derive runtime information. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext.
    fun JS::Handle<JSFunction*> * Function to decompile.

    Description

    JS_DecompileFunction generates the complete source code of a function declaration from a function's compiled form, fun.

    If successful, JS_DecompileFunction returns a string containing the text of the function. Otherwise, it returns NULL.

    If you decompile a function that does not make a native C call, then the text created by JS_DecompileFunction is a complete function declaration suitable for re-parsing. If you decompile a function that makes a native C call, the body of the function contains the text "native code'" and cannot be re-parsed.
