site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com User-agent: Microsoft-Entourage/10.1.6.040913.0 Under 10.3.6, I'm obtaining an instance of CFMutableDictionaryRef by passing kIOUSBDeviceClassName to IOServiceMatching. When I launch my app from a terminal, this works fine. I pass the dictionary to CFShow and get the output I would expect. However, when my app is launched as a startup item, CFShow outputs *nothing* (and the CFMutableDictionaryRef isn't good for anything; for example, CFShow still outputs nothing after I call CFDictionarySetValue). So I logged some pertinent data about the dictionary. launch context CFMutableDictionaryRef first 12 bytes ============== ====================== ======================== Terminal 6323872 006004700001039500000001 Startup Item 4214160 004004400001039500000001 Does anybody have any insight into the significance of these differences or any other insight into why IOServiceMatching might produce such an oddly inert dictionary? -- Pete Gontier http://www.m-audio.com/ _______________________________________________ Do not post admin requests to the list.
