SecKeychainAttributeInfoForItemID(_:_:_:)

Obtains tags for all possible attributes of a given item class.

Declaration

func SecKeychainAttributeInfoForItemID(_ keychain: SecKeychain?, _ itemID: UInt32, _ info: UnsafeMutablePointer<UnsafeMutablePointer<SecKeychainAttributeInfo>?>) -> OSStatus

Parameters

keychain:
A keychain object.
itemID:
The relation identifier of the item tags. An itemID is a CSSM_DB_RECORDTYPE type as defined in cssmtype.h.
info:
On return, a pointer to the keychain attribute information. Your application should call the Seckeychainfreeattributeinfo(_:) function to release this structure when done with it.

Return Value

A result code. See Security Framework Result Codes.

Discussion

This call returns more attributes than are supported by the old style Keychain API and passing them into older calls yields an invalid attribute error. The recommended call to retrieve the attribute values is the SecKeychainItemCopyAttributesAndData(_:_:_:_:_:_:) function.
