_LWP_DETACH(2) BSD System Calls Manual _LWP_DETACH(2)
_lwp_detach -- detach a light-weight process
Standard C Library (libc, -lc)
_lwp_detach() causes a light-weight process to become detached, having the same effect as if
the LWP was created with the LWP_DETACHED flag.
The resources associated with a detached LWP will be automatically reclaimed by the system
when the LWP exits. Conversely, an attached LWP's resources will not be reclaimed until its
status is reported to another LWP via _lwp_wait(2).
A 0 value indicates that the call succeeded. A -1 return value indicates an error occurred
and errno is set to indicate the reason.
[EINVAL] The LWP is already detached.
[ESRCH] No LWP can be found in the current process corresponding to that specified by lwp.
The _lwp_detach() system call first appeared in NetBSD 5.0.
