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().
