On Unix-like and other POSIX operating systems, the sleep() function is called providing a single parameter of type unsigned integer of the number of seconds to sleep. [3] A higher-precision version is the nanosleep() function and the now deprecated usleep. [4] POSIX also allows for choosing clock sources via the extended version clock ...
In the Solaris implementation of condition variables, a spurious wakeup may occur without the condition being assigned if the process is signaled; the wait system call aborts and returns EINTR. [2] The Linux p-thread implementation of condition variables guarantees that it will not do that. [3] [4]
A sleep command is also part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2. [8] In PowerShell, sleep is a predefined command alias for the Start-Sleep cmdlet which serves the same purpose. [9] Microsoft also provides a sleep resource kit tool for Windows which can be used in batch files or the command prompt to pause the execution and wait ...
Busy-waiting itself can be made much less wasteful by using a delay function (e.g., sleep()) found in most operating systems. This puts a thread to sleep for a specified time, during which the thread will waste no CPU time. If the loop is checking something simple then it will spend most of its time asleep and will waste very little CPU time.
On any multi-processor system that uses the MESI contention protocol, such a test-and-test-and-set lock (TTAS) performs much better than the simple test-and-set lock (TAS) approach. [ 4 ] With large numbers of processors, adding a random exponential backoff delay before re-checking the lock performs even better than TTAS.

In the Microsoft Windows and ReactOS [2] command-line interfaces, the timeout command pauses the command processor for the specified number of seconds. [3] [4] In POP connections, the server will usually close a client connection after a certain period of inactivity (the timeout period). This ensures that connections do not persist forever, if ...
