_LWP_MAKECONTEXT(3)     NetBSD 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 implemen-
     tation of _lwp_makecontext().
