quickCheck* functions writes results to stderr & stdout, but I don't want them written to the app's original stdout/err. (I'm using SafeHaskell features to avoid malicious code executed, so don't worry about that :-))
So I want to execute I/O action hijacking stdout/err in a thread-safe manner. For example, I need function like below:
Handles are process level, not thread level, in all supported operating systems. If something is writing to stderr then it is writing to a process level entity and there is no way to capture it at the level of a thread. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
