# encoding: utf-8 # module _signal # from (built-in) # by generator 1.147 """ 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.
