_LWP_DETACH(2)                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.
