On POSIX-compliant platforms, SIGINT is the signal sent to a process by its controlling terminal when a user wishes to interrupt the process. In source code, SIGINT is a symbolic constant defined in the header file signal.h. Symbolic signal names are used because a signal's numeric value can vary across platforms; on the vast majority of systems, it is signal #2
[edit] Etymology
SIG is a common prefix for signal names. INT is an abbreviated form of interrupt.
SIGINT is sent when the user on the process' controlling terminal presses the interrupt the running process key — typically Control-C, but on some systems, the "delete" character or "break" key.
