_lwp_makecontext(2)
NAME
_lwp_makecontext - initialize an LWP context
SYNOPSIS
#include <sys/types.h>
#include <sys/lwp.h>
#include <ucontext.h>
void _lwp_makecontext(ucontext_t *ucp, void
(*start_routine)(void *), void *arg, void *private, caddr_t
stack_base, size_t stack_size);
DESCRIPTION
The _lwp_makecontext() function initializes the user context
structure pointed to by ucp. The user context is defined by
ucontext(3HEAD). The resulting user context can be used by
_lwp_create(2) for specifying the initial state of the new
LWP. The user context is set up to start executing the func-
tion start_routine with a single argument, arg, and to call
_lwp_exit(2) if start_routine returns. The new LWP will use
the storage starting at stack_base and continuing for
stack_size bytes as an execution stack. The initial value in
LWP-private memory will be set to private (see
_lwp_setprivate(2)). The signal mask in the user context is
not initialized.
