It seems some casting is required for this though?
JSValueRef JSObjectCallAsFunction( JSContextRef ctx, JSObjectRef object, JSObjectRef thisObject, size_t argumentCount, const JSValueRef arguments[], JSValueRef *exception); The above function accepts a JSObjectRef object. However JSValueRef JSObjectGetProperty( JSContextRef ctx, JSObjectRef object, JSStringRef propertyName, JSValueRef *exception); returns JSValueRef Looking at the typedefs in APICast.h typedef const struct OpaqueJSValue* JSValueRef; typedef struct OpaqueJSValue* JSObjectRef; If I didn't cast, then wouldn't I be attempting to pass a const value into a function that accepts a non-const parameter? It is however reporting a compilation error because the types don't' match, On Mon, Jun 1, 2009 at 2:53 PM, Kalle Vahlman <kalle.vahl...@gmail.com> wrote: > 2009/6/1 Jack Wootton <jackwoot...@gmail.com>: >> Hi all, > > Hi! > >> I'm attempting to use the function JSObjectMakeFunction described here: >> >> http://gemma.apple.com/documentation/Carbon/Reference/WebKit_JavaScriptCore_Ref/JSObjectRef/index.html >> >> I would like to call a JavaScript function from C.
