System.Threading.Timer Public Timer (TimerCallback callback, object state, int duetime, int period); The callback delegate will be repeated over the period interval, and the state parameter can pass in the object that you want to handle in the callback delegate, duetime how long after callback starts execution, period how often the callba

The purpose of using a timer is to perform a task periodically, or to perform a task at a specified time. In order to achieve this goal, there are generally two common and more effective methods.

Create a Timer: Int timer_create (clockid_t clock_id, struct sigevent * EVP, timer_t * timerid) A process can call timer_create () to create a specific timer, which is owned by each process rather than inherited during fork. Clock_id indicates the clock on which the timer is based. * timerid loads the ID of the created timer
