bundle_wait - wait while coroutines in the bundle finish
#include <libdill.h> int bundle_wait( int bndl, int64_t deadline);
If there are no coroutines in the bundle the function will succeed immediately. Otherwise, it will wait until all the coroutines in the bundle finish or until deadline is reached.
bndl: Handle of a coroutine bundle.
deadline: A point in time when the operation should time out, in milliseconds. Use the now function to get your current point in time. 0 means immediate timeout, i.e., perform the operation if possible or return without blocking if not. -1 means no deadline, i.e., the call will block forever if the operation cannot be performed.
In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below.
int b = bundle(); bundle_go(b, worker()); bundle_go(b, worker()); bundle_go(b, worker()); /* Give wrokers 1 second to finish. */ bundle_wait(b, now() + 1000); /* Cancel any remaining workers. */ hclose(b);
