Synopses

Declared in <bslmt_latch.h>

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. Optionally specify a clockType indicating the type of the system clock against which the bsls::TimeInterval absTime timeouts passed to the timedWait method are to be interpreted. If clockType is not specified then the realtime system clock is used. The behavior is undefined unless 0 <= count.

    bsls::SystemClockType::Enum clockType = bsls::SystemClockType::e_REALTIME);

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 monotonic 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.

Latch(
    int count,
    std::chrono::steady_clock const&);
