Hi there, I am having a strange problem that other people don't seem to be having because I can't find any references to in google searches. I am using MacRuby 0.4 installed from the binary available on the macruby binary releases page (MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]) I have an application which stores username/passwords in the keychain. I can add items to the keychain (so I can call SecKeychainAddGenericPassword() fine and therefore I think my setup must be OK), but I cannot retrieve them. When I call: status, *data = SecKeychainFindGenericPassword( nil, service.length, service, username.length, username) I get an error: Configuration.app/Contents/Resources/Controller.rb:99:in `SecKeychainFindGenericPassword': wrong number of arguments (5 for 8) (ArgumentError) The method signature is this: OSStatus SecKeychainFindGenericPassword ( CFTypeRef keychainOrArray, UInt32 serviceNameLength, const char *serviceName, UInt32 accountNameLength, const char *accountName, UInt32 *passwordLength, void **passwordData, SecKeychainItemRef *itemRef ); All the examples I've read suggest that this method in macruby should only take 5 args and return the status, password length, password string and item reference (the last 3 extracted from *data) instead of passing in pointers (which I don't know how to do BTW). What gives? Anyone have any idea or had the same problem? -- Karl Varga kjvarga@gmail.com Cell: +61 (0)4 2075 1356
