_LWP_MAKECONTEXT(3)					   BSD Library Functions Manual 				       _LWP_MAKECONTEXT(3)

NAME

     _lwp_makecontext -- create a new initial light-weight process execution context

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <lwp.h>

     void
     _lwp_makecontext(ucontext_t *context, void (*start_routine)(void *), void *arg, void *private, caddr_t stack_base, size_t stack_size);

DESCRIPTION

     _lwp_makecontext() initializes the context structure pointed to by context in a manner suitable for using with _lwp_create(2).  The LWP will
     begin execution at the function specified by start_routine which will be passed a single argument arg.  The LWP private data pointer will be
     set to private.  The stack region for the new LWP is specified by the stack_base and stack_size arguments.

     The signal mask in the context structure is not initialized by _lwp_makecontext().

SEE ALSO

     _lwp_create(2), _lwp_getprivate(2)

HISTORY

     The _lwp_create() system call first appeared in NetBSD 2.0.

BUGS

     The LWP private data pointer is not initialized by the current implementation of _lwp_makecontext().

_LWP_WAIT(2)						      BSD System Calls Manual						      _LWP_WAIT(2)

NAME

     _lwp_wait -- wait for light-weight process termination

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <lwp.h>

     int
     _lwp_wait(lwpid_t wlwp, lwpid_t *rlwp);

DESCRIPTION

     _lwp_wait() suspends execution of the calling LWP until the LWP specified by wlwp terminates.  The specified LWP must not be detached.  If
     wlwp is 0, then _lwp_wait() waits for any undetached LWP in the current process.

     If rlwp is not NULL, then it points to the location where the LWP ID of the exited LWP is stored.

RETURN VALUES

     Upon successful completion, _lwp_wait() returns a value of 0.  Otherwise, an error code is returned to indicate the error.

ERRORS

     _lwp_wait() will fail if:

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

     [EDEADLK]	The calling LWP is the only LWP in the process.

     [EDEADLK]	The LWP ID specified by wlwp is the LWP ID of the calling LWP.

     [EINTR]	_lwp_wait() was interrupted by a caught signal, or the signal did not have the SA_RESTART flag set.

     The _lwp_wait() system call first appeared in NetBSD 2.0.
