#1049: Can't get the event path from FSEventStreamCallback ---------------------------+------------------------------------------------ Reporter: haxie1@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ---------------------------+------------------------------------------------ Comment(by lsansonetti@…): The callback is defined like this: {{{ typedef void ( *FSEventStreamCallback )( ConstFSEventStreamRef streamRef, void *clientCallBackInfo, size_t numEvents, void *eventPaths, const FSEventStreamEventFlags eventFlags[], const FSEventStreamEventId eventIds[]); }}} Here, eventPaths is a void pointer, so MacRuby will give you a Pointer object. However, apparently, it looks like FSEvents will yield an NSArray instead, in this snippet. In C, one would simply cast eventPaths as an NSArray, but in MacRuby, this isn't possible. Using #cast! on the Pointer will simply change the pointer type, and in your case, you're getting what an NSArray structure points to as its first pointer field, which is the isa (class). -- Ticket URL: <http://www.macruby.org/trac/ticket/1049#comment:1> MacRuby <http://macruby.org/>
