Declaration of the Trigger class for the General Utility Library.
A class that allows sending triggers and waiting for them across different threads.
Definition: Trigger.h:111
bool wait_for(const std::chrono::duration< Rep, Period > &delta_t) const
Suspend execution of the current thread until the trigger goes high (true) or at least the given time...
Definition: Trigger.h:189
auto toc(std::chrono::steady_clock::time_point t0)
Return the elapsed time in seconds (or a different unit) since the given time point.
Definition: time_util.h:92
bool sleep(const std::chrono::duration< Rep, Period > &duration, const Trigger &trg)
Sleep for at least the given time span, with the option of being woken up from another thread.
Definition: time_util.h:114
std::chrono::steady_clock::time_point tic()
Return the current time as a std::chrono time_point.
Definition: time_util.h:54
Definition of macros used internally by GUL.
Namespace gul14 contains all functions and classes of the General Utility Library.
