Sleeping
|
|
|
Sleep for the specified duration (in seconds). Returns the time remaining
(if the sleep was interrupted by a signal, for example).
GHC Note: the comment for usleep also applies here.
|
|
|
Sleep for the specified duration (in microseconds).
GHC Note: Control.Concurrent.threadDelay is a better choice.
Without the -threaded option, usleep will block all other user
threads. Even with the -threaded option, usleep requires a
full OS thread to itself. Control.Concurrent.threadDelay has
neither of these shortcomings.
