[MacRuby-devel] Using 'Pointer.new_with_type'

Hi all, Is there a particular framework that's required in order to use 'Pointer.new_with_type'? I'm using the trunk (build 809) and it's apparently not available in either my Xcode project or in macirb. Is there an alternative method for working with pointers? My specific case is that I want to call the C function mkstemp. Is this what I should be doing? : @tmpfInfo += "/"+"resynch.fileinfo.XXXXXX" tmptr = Pointer.new_with_type('*') tmptr.assign(@tmpfInfo) fd_tmpInfo = mkstemp(tmptr) tmpInfoFileHandle = NSFileHandle.initWithFileDescriptor(@fd_tmpInfo) Michael
