Imports

cpp	Provides classes and predicates for working with C/C++ code.

Predicates

lockCall	Holds if `call` is a call that locks or tries to lock its argument `arg`.
mustlockCall	Holds if `call` is a call that always locks its argument `arg`.
trylockCall	Holds if `call` is a call that tries to lock its argument `arg`, but may return without success.
unlockCall	Holds if `call` is a call that unlocks its argument `arg`.

Classes

DefaultMutexType	A class or struct type that has both a lock and an unlock function candidate, and is therefore a mutex.
MutexType	A type that acts as a mutex. This class is extended below and and may be extended in `Options.qll`.
