_LWP_DETACH(2) BSD System Calls Manual _LWP_DETACH(2)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.
