"""Script used to test os.kill on Windows, for issue #1220212
|
|
|
|
This script is started as a subprocess in test_os and is used to test the
|
|
CTRL_C_EVENT and CTRL_BREAK_EVENT signals, which requires a custom handler
|
|
to be written into the kill target.
|
|
|
|
See http://msdn.microsoft.com/en-us/library/ms685049%28v=VS.85%29.aspx for a
|
|
similar example in C.
