I suppose you could try setting up an un-named pipe (which returns two
file-descriptors), forking into two processes, and then you have
communication established, since one process can use one file-descriptor,
and the other can use the other file descriptor to communicate with each
other,
then use one process to run the loop, and the other to wait for input...
then, when input happens, get the process to write the input to the pipe...
you can then get the printf'ing process to keep checking to see if there is
a character in the pipe, and if there is, to break out of the loop...
