_LWP_DETACH(2) FreeBSD 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
The _lwp_detach() function returns the value 0 if successful; otherwise
the value -1 is returned and the global variable errno is set to indicate
the error.
ERRORS
[EINVAL] The LWP is already detached.
[ESRCH] No LWP can be found in the current process
corresponding to that specified by lwp.
