Usually capitalized, but may appear as "abend". Some common ABEND codes are System ABEND 0C7 (data exception) and System ABEND 0CB (division by zero). [1] [2] [3] Abends can be "soft" (allowing automatic recovery) or "hard" (terminating the activity). [4] The term is jocularly claimed to be derived from the German word "Abend" meaning "evening ...
The raise(3) library function sends the specified signal to the current process. Exceptions such as division by zero, segmentation violation , and floating point exception will cause a core dump and terminate the program. The kernel can generate signals to notify processes of events.
The return value from main is passed to the exit function, which for values zero, EXIT_SUCCESS or EXIT_FAILURE may translate it to "an implementation defined form" of successful termination or unsuccessful termination. [citation needed] Apart from zero and the macros EXIT_SUCCESS and EXIT_FAILURE, the C standard does not define the meaning of ...
TCP is connection-oriented, meaning that sender and receiver firstly need to establish a connection based on agreed parameters; they do this through three-way handshake procedure. [1] The server must be listening (passive open) for connection requests from clients before a connection is established.
The concept of a single point of failure has also been applied to fields outside of engineering, computers, and networking, such as corporate supply chain management [6] and transportation management. [7] Design structures that create single points of failure include bottlenecks and series circuits (in contrast to parallel circuits).
The definition of an exception is based on the observation that each procedure has a precondition, a set of circumstances for which it will terminate "normally". [1] An exception handling mechanism allows the procedure to raise an exception [ 2 ] if this precondition is violated, [ 1 ] for example if the procedure has been called on an abnormal ...

One specific DLE event signals the end of a fax page, or the end of an audio file. That event returns the modem back into command mode. Unlike in standard dial-up data mode, dropping DTR isn't an appropriate way to resume command mode since a hangup is not desired, and an escape code with mandatory pauses isn't suitable either.
