wait
Description:
public int wait (
ClockTime timeout)
Wait for activity on the file descriptors in set.
This function waits up to the specified timeout. A timeout of
CLOCK_TIME_NONE waits forever.
For Poll objects created with
Poll, this function can only be called from a single thread at a time.
If called from multiple threads, -1 will be returned with errno set to EPERM.
This is not true for timer Poll objects created with
Poll.timer, where it is allowed to have multiple threads waiting
simultaneously.
Parameters:
| timeout |
a timeout in nanoseconds. |
Returns:
The number of PollFD in set that have activity or 0 when no
activity was detected after timeout. If an error occurs, -1 is returned and errno is set. |
