Synopsis

Declared in <absl/synchronization/blocking_counter.h>

DecrementCount();

Description

Memory ordering: For any threads X and Y, any action taken by X before it calls DecrementCount() is visible to thread Y after Y's call to DecrementCount(), provided Y's call returns true.

Return Value

true if the counter reached zero as a result of this call.
