17 * 11/22/99 aliu Make non-global mutex autoinitialize [j151]
26 * ICU Mutex wrappers. Wrap operating system mutexes, giving the rest of ICU a
27 * platform independent set of mutex operations. For internal ICU use only.
70 // Unknown platform. Note that user can still set mutex functions at run time.
77 // The ICU global mutex. Used when ICU implementation code passes NULL for the mutex pointer.
80 // Implementation mutex. Used for compare & swap when no intrinsic is available, and
99 * User mutex implementation functions. If non-null, call back to these rather than
133 * User mutex lock.
135 * User mutexes need to be initialized before they can be used. We use the impl mutex
