from python, cancelling C script using "ctr c" signal to command line

Question

i call a python script from a C script using a system call (i know this isn't best practice, but for now it does the intended job).

while the C is running at the command line, i can cancel it using Ctrl-C.

when i am running the python script, when the code follows into particular if clauses, i would like to cancel the C script using a Ctr-C call to the command line, the same as if i could do it manually.

is this possible please?

It sound like the C program is waiting for the python program to finish, you need to catch the keyboard interrupt in C and pass it onto the python process, or trigger one in the python process — Daniel Rucci, Aug 29 '12 at 14:08
