Create a latch for count events using the realtime clock.
Synopsis
Declared in <bslmt_latch.h>
Latch(
int count,
std::chrono::system_clock const& systemClock);Description
Create a latch that will synchronize on the specified count number of events, and when count events have been recorded will release any waiting threads. Use the realtime system clock as the clock against which the absTime timeouts passed to the timedWait methods are interpreted (see {Supported Clock‐Types} in the component‐level documentation). The behavior is undefined unless 0 <= count.
