Interrupting `while loop` with keyboard in Cython
- by linello
I want to be able to interrupt a long function with cython, using the usual CTRL+C interrupt command.
My C++ long function is repeatedly called inside a while loop from Cython code, but I want to be able, during the loop, to send an "interrupt" and block the while loop.
The interrupt also should wait the longFunction() to finish, so that no data are lost or kept in unknown status.
This is one of my first implementation, which obviously doesn't work:
computed=0;
print "Computing long function..."
while ( computed==0 ):
try:
computed = self.thisptr.aLongFunction()
except (KeyboardInterrupt, SystemExit):
computed=1
print '\n! Received keyboard interrupt.\n'
break;
(p.s. self.thisptr is the pointer to the current class which implements aLongFunction() )
