| 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. It |
| provides no memory barriers. |
