The delay() function is built upon a C library function called
clock()
. The clock() function returns a time value in clock ticks, which is based on the processor’s speed. The value returned is of the clock_t variable type. You can use subsequent reads of the clock() function to determine elapsed time.
What is sleep () in C?
The function sleep gives a simple way to make the
program wait for a short interval
. … The sleep function waits for seconds seconds or until a signal is delivered, whichever happens first. If sleep returns because the requested interval is over, it returns a value of zero.

Why delay is used in Arduino?

a blocking function
. Blocking functions prevent a program from doing anything else until that particular task has completed. If you need multiple tasks to occur at the same time, you simply cannot use delay().
How do you create a delay function?
Create a Simple Delay Using
setTimeout
log(“Hello”); setTimeout(() => { console. log(“World!”); }, 2000); This would log “Hello” to the console, then after two seconds “World!” And in many cases, this is enough: do something, wait, then do something else. Sorted!

defines macros such as WEXITSTATUS so that they will work on either kind of object, and the wait function is defined to accept either type of pointer as its status-ptr argument. These functions are declared in `sys/wait.
What is Pid_t PID?
pid_t data type
stands for process identification
and it is used to represent process ids. Whenever, we want to declare a variable that is going to be deal with the process ids we can use pid_t data type. The type of pid_t data is a signed integer type (signed int or we can say int).
How does delay work?
Delay works
by simply sending an audio signal to a recording medium then repeating it over a determined length of time
