SIGINT (POSIX)
From Wikipedia, the free encyclopedia
| Description: | Terminal interrupt signal |
|---|---|
| Default action: | Abnormal termination of the process |
| SA_SIGINFO macros | |
| None | |
On POSIX-compliant platforms, SIGINT is the signal thrown by a computer program when a user wishes to interrupt a 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
SIG is a common prefix for signal names. INT is an abbreviated form of interrupt or interactive.
SIGINT is sent when the user on the process' terminal presses the interrupt the running process key — typically Control-C, but on some systems, the "delete" character or "break" key (the latter is not an ASCII character, but an out-of-band signal such as an electrical condition on a serial port).
