In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
Standard input is a stream from which a program reads its input data. The program requests data transfers by use of the read operation. Not all programs require stream input.
enter the monitor: enter the method if the monitor is locked add this thread to e block this thread else lock the monitor leave the monitor: schedule return from the method wait c: add this thread to c.q schedule block this thread notify c: if there is a thread waiting on c.q select and remove one thread t from c.q (t is called "the notified ...
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. Problems of this nature can therefore ...
In signal processing, control theory, electronics, and mathematics, overshoot is the occurrence of a signal or function exceeding its target. Undershoot is the same phenomenon in the opposite direction.

The second scheme, and the one implemented in many production-quality C++ compilers and 64-bit Microsoft SEH, is a table-driven approach. This creates static tables at compile time and link time that relate ranges of the program counter to the program state with respect to exception handling. [22]
Segmentation faults can also occur independently of page faults: illegal access to a valid page is a segmentation fault, but not an invalid page fault, and segmentation faults can occur in the middle of a page (hence no page fault), for example in a buffer overflow that stays within a page but illegally overwrites memory.
