NAME
_lwp_detach —
detach a light-weight
process
LIBRARY
Standard C Library (libc, -lc)
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.
