nsIUUIDGenerator is implemented by a service that can generate
universally unique identifiers, ideally using any platform-native
method for generating UUIDs.
Obtains a new UUID using appropriate platform-specific methods to
obtain a nsID that can be considered to be globally unique.
@throws NS_ERROR_FAILURE if a UUID cannot be generated (e.g. if
an underlying source of randomness is not available)
| an nsID filled in with a new UUID. |
Obtain a new UUID like the generateUUID method, but place it in
the provided nsID pointer instead of allocating a new nsID.
@throws NS_ERROR_FAILURE if a UUID cannot be generated (e.g. if
an underlying source of randomness is not available)
| id | an existing nsID pointer where the UUID will be stored. |
