Detailed Description

Since nearly every method within the Wiselib returns at least, if the call was successful or not, the concept for the Basic Return Values defines constants for success and failure.

Derived concepts may define more fine-grained failure values (which are not allowed to equal SUCCESS or ERR_UNSPEC).
