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`.

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`.
