| r584 | """This module provides mechanisms to use signal handlers in Python. | |||
| Functions: | ||||
| alarm() -- cause SIGALRM after a specified time [Unix only] | ||||
| setitimer() -- cause a signal (described below) after a specified | ||||
| float time and the timer may restart then [Unix only] | ||||
| getitimer() -- get current value of timer [Unix only] | ||||
| signal() -- set the action for a given signal | ||||
| getsignal() -- get the signal action for a given signal | ||||
| pause() -- wait until a signal arrives [Unix only] | ||||
| default_int_handler() -- default SIGINT handler | ||||
| signal constants: | ||||
| SIG_DFL -- used to refer to the system default handler | ||||
| SIG_IGN -- used to ignore the signal | ||||
| NSIG -- number of defined signals | ||||
| SIGINT, SIGTERM, etc. -- signal numbers | ||||
| itimer constants: | ||||
| ITIMER_REAL -- decrements in real time, and delivers SIGALRM upon | ||||
| expiration | ||||
| ITIMER_VIRTUAL -- decrements only when the process is executing, | ||||
| and delivers SIGVTALRM upon expiration | ||||
| ITIMER_PROF -- decrements both when the process is executing and | ||||
| when the system is executing on behalf of the process. | ||||
| Coupled with ITIMER_VIRTUAL, this timer is usually | ||||
| used to profile the time spent by the application | ||||
| in user and kernel space. SIGPROF is delivered upon | ||||
| expiration. | ||||
| *** IMPORTANT NOTICE *** | ||||
| A signal handler function is called with two arguments: | ||||
| the first is the signal number, the second is the interrupted stack frame.""" | ||||
