Thread Management in OSX Command Line C Application

Thread Management in OSX Command Line C Application

I am learning Mac App development, starting with command line applications
and the Core Foundation API. What I am wanting to do is listen for file
system events while the application is running in the terminal. When the
user quits, it cleanly shuts down the stream and exits. Here is what I
have...
#include <CoreServices/CoreServices.h>
#include <stdio.h>
void eventCallback(FSEventStreamRef stream, void *callbackInfo, size_t
numEvents, void *paths, FSEventStreamEventFlags flags[],
FSEventStreamEventId eventId[]) {
printf("Test");
}
int main(int argc, const char * argv[])
{
CFStringRef mypath = CFSTR("/Path/to/folder");
CFArrayRef paths = CFArrayCreate(NULL, (const void **)&mypath, 1, NULL);
CFRunLoopRef loop = CFRunLoopGetMain();
FSEventStreamRef stream = FSEventStreamCreate(NULL, eventCallback,
NULL, paths, kFSEventStreamEventIdSinceNow, 3.0,
kFSEventStreamCreateFlagNone);
FSEventStreamScheduleWithRunLoop(stream, loop, kCFRunLoopDefaultMode);
FSEventStreamStart(stream);
bool done;
# Somehow put main thread to sleep here...
# On exit of application
FSEventStreamStop(stream);
FSEventStreamInvalidate(stream);
FSEventStreamRelease(stream);
return 0;
}
So I've determined that using either the main threads run loop (or maybe a
separate thread) should do this work, but I am not sure the best way in
which to put the thread to sleep while waiting for events. I am not
familiar enough with Apple's API to know what to do.
Thanks for any help!
