- The signal module now supports SIGBREAK on Windows, thanks to Steven

Scott. Note that SIGBREAK is unique to Windows. The default SIGBREAK

action remains to call Win32 ExitProcess(). This can be changed via

signal.signal(). For example:

# Make Ctrl+Break raise KeyboardInterrupt, like Python's default Ctrl+C

# (SIGINT) behavior.

import signal

signal.signal(signal.SIGBREAK,

signal.default_int_handler)

try:

while 1:

pass

except KeyboardInterrupt:

# We get here on Ctrl+C or Ctrl+Break now; if we had not changed

# SIGBREAK, only on Ctrl+C (and Ctrl+Break would terminate the

# program without the possibility for any Python-level cleanup).

print "Clean exit"

#ifdef SIGBREAK

x = PyInt_FromLong(SIGBREAK);

PyDict_SetItemString(d, "SIGBREAK", x);

Py_XDECREF(x);
