// A library to manage RLZ information for access-points shared
// across different client applications.
//
// All functions return true on success and false on error.
// This implemenation is thread safe.
//
// Each prototype mentions the registry access requirements:
//
// HKLM read:  Will work from any process and at any privilege level on Vista.
// HKCU read:  Calls made from the SYSTEM account must pass the current user's
//             SID as the optional 'sid' param. Can be called from low integrity
//             process on Vista.
// HKCU write: Calls made from the SYSTEM account must pass the current user's
//             SID as the optional 'sid' param. Calls require at least medium
//             integrity on Vista (e.g. Toolbar will need to use their broker)
// HKLM write: Calls must be made from an account with admin rights. No SID
//             need be passed when running as SYSTEM.
// Functions which do not access registry will be marked with "no restrictions".

// Testing RLZ requires reading and writing to the Windows registry.  To keep
// the tests isolated from the machine's state, as well as to prevent the tests
// from causing side effects in the registry, HKCU and HKLM are overridden for
// the duration of the tests. RLZ tests don't expect the HKCU and KHLM hives to
// be empty though, and this function initializes the minimum value needed so
// that the test will run successfully.
//
// The two arguments to this function should be the keys that will represent
// the HKLM and HKCU registry hives during the tests.  This function should be
// called *before* the hives are overridden.
