In a computer or data transmission system, to abort means to terminate, usually in a controlled manner, a processing activity because it is impossible or undesirable for the activity to proceed or in conjunction with an error.
Such an action may be accompanied by diagnostic information on the aborted process.
Specifically in the context of data transmission, an abort is a function invoked by a sending station to cause the recipient to discard or ignore all bit sequences transmitted by the sender since the preceding flag sequence.
In the C programming language, abort() is a standard library function that terminates the current application and returns an error code to the host environment.
[2] Aborts are typically logged, especially in critical systems, to facilitate troubleshooting and improve future runs.
