For example, a useful pair of contracts, allowing occupancy to be passed without establishing the invariant, is: wait c: precondition I modifies the state of the monitor postcondition P c signal c precondition (not empty(c) and P c) or (empty(c) and I) modifies the state of the monitor postcondition I (See Howard [4] and Buhr et al. [5] for more.)
In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
setjmp.h is a header defined in the C standard library to provide "non-local jumps": control flow that deviates from the usual subroutine call and return sequence. The complementary functions setjmp and longjmp provide this functionality.
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space. Furthermore, the actual page contents may need to be loaded from a back-up, e.g. a disk.
The memory model defined in the C11 and C++11 standards specify that a C or C++ program containing a data race has undefined behavior. [ 3 ] [ 4 ] A race condition can be difficult to reproduce and debug because the end result is nondeterministic and depends on the relative timing between interfering threads.

CP/M, [3] originally standing for Control Program/Monitor [4] and later Control Program for Microcomputers, [5] [6] [7] is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system [8] and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
