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.
C Shell running on Windows Services for UNIX. The C shell (csh or the improved version, tcsh) is a Unix shell created by Bill Joy while he was a graduate student at University of California, Berkeley in the late 1970s.
In computing, direct or immediate mode [1] [2] in an interactive programming system is the immediate execution of commands, statements, or expressions.In many interactive systems, most of these can both be included in programs or executed directly in a read–eval–print loop (REPL).
In his book The Humane Interface, Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state."
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.
In cooked mode, the terminal line discipline processes the characters "ABC<Backspace>D" and presents only the result ("ABD") to the program. Technically, the term "cooked mode" should be associated only with streams that have a terminal line discipline , but generally it is applied to any system that does some amount of preprocessing.

Some RW locks allow the lock to be atomically upgraded from being locked in read-mode to write-mode, as well as being downgraded from write-mode to read-mode. Upgrading a lock from read-mode to write-mode is prone to deadlocks, since whenever two threads holding reader locks both attempt to upgrade to writer locks, a deadlock is created that ...
