/** Synchronization primitives for GPR.
|
|
|
|
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.
