Mounting a file containing a file system via such a loop mount makes the files within that file system accessible. They appear in the mount point directory. A loop device may allow some kind of data elaboration during this redirection. For example, the device may be the unencrypted version of an encrypted file.
The basic idea of loop unrolling is that the number of instructions executed in a loop can be reduced by reducing the number of loop tests, sometimes reducing the amount of time spent in the loop. For example, in the case of a loop with only a single instruction in the block code, the loop test will typically be performed for every iteration of ...
The following C code examples illustrate two threads that share a global integer i. The first thread uses busy-waiting to check for a change in the value of i : #include <pthread.h> #include <stdatomic.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> /* i is global, so it is visible to all functions.
One common cause, for example, is that a programmer intends to iterate over sequence of nodes in a data structure such as a linked list or tree, executing the loop code once for each node. Improperly formed links can create a reference loop in the data structure, where one node links to another that occurs earlier in the sequence.

Many operating systems, for example Windows, [1] Linux, [2] and macOS [3] will run an idle task, which is a special task loaded by the OS scheduler on a CPU when there is nothing for the CPU to do. The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority.
