_LWP_WAKEUP(2) BSD System Calls Manual _LWP_WAKEUP(2)
_lwp_wakeup -- make a blocked light-weight process runnable
Standard C Library (libc, -lc)
_lwp_wakeup() makes a blocked LWP runnable. The blocked LWP must be in LSSLEEP state.
Unblocking the LWP does not guarantee that it will make progress; it may block again as soon
as it resumes execution in the kernel.
Upon successful completion, _lwp_wakeup() returns a value of 0. Otherwise, an error code is
returned to indicate the error.
_lwp_wakeup() will fail if:
[ESRCH] No LWP can be found in the current process corresponding to that specified by lwp.
[ENODEV] The specified LWP is not in LSSLEEP state.
[EBUSY] The specified LWP is blocked in an uninterruptible sleep.
The _lwp_wakeup() system call first appeared in NetBSD 2.0.
