Blocks the execution of the current thread for at least the specified sleep_duration
.
This function may block for longer than sleep_duration
due to scheduling or resource contention delays.
The standard recommends that a steady clock is used to measure the duration. If an implementation uses a system clock instead, the wait time may also be sensitive to clock adjustments.
At least prevent the current thread of execution within a specified sleep_duration.
Due to scheduling or resource contention delay, this feature may be blocked longer than sleep_duration.
The standard recommends using a stable clock to measure the duration. If implemented in place of the system clock, the latency may also be sensitive to clock adjustment.
