The type gpr_mu provides a non-reentrant mutex (lock). The type gpr_cv provides a condition variable. The type gpr_once provides for one-time initialization. The type gpr_event provides one-time-setting, reading, and waiting of a void*, with memory barriers. The type gpr_refcount provides an object reference counter, with memory barriers suitable to control object lifetimes. The type gpr_stats_counter provides an atomic statistics counter.
