_LWP_DETACH(2)

NAME
_lwp_detach - detach a light-weight process

LIBRARY
libc

SYNOPSIS
#include <lwp.h>
int
_lwp_detach(lwpid_t lwp);

DESCRIPTION
_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).

RETURN VALUES
A 0 value indicates that the call succeeded. A -1 return value indicates an error occurred and errno is set to indicate the reason.

ERRORS

[EINVAL]
    The LWP is already detached.

[ESRCH]
    No LWP can be found in the current process corresponding to that specified by lwp.

HISTORY
The _lwp_detach() system call first appeared in NetBSD 5.0.
