getclktck
The getclktck function is a system call or library function used in some operating systems to retrieve the system's clock tick count. The clock tick is the fundamental unit of time measurement for the operating system's internal timers. This count typically starts at zero when the system boots and increments with each tick generated by the hardware timer. The frequency of these ticks, known as the clock tick rate or frequency, is system-dependent and determines the granularity of time measurements within the operating system.
Applications might use getclktck to understand the system's uptime or to perform time-based calculations where a
