during developing a dashboard widget that requires an interactive use
with OS X shell, I have found out that simply using NSTask doesn't work
for certin uses I need.
so, in search for a solution, I have found a class which does exactly what I need:
PTYTask what this class does is to fork a PTY process and then provide an interface to it, kind of like NSTask
the problem is that when debugging using gdb, the following error appears a lot of times:
The process has forked and you cannot use this CoreFoundation
functionality safely. You MUST exec().
Break on
__THE_PROCESS_HAS_FORKED_AND_
YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__()
to debug.
what does this mean and what can I do with that?
