_LWP_UNPARK(2)						      BSD System Calls Manual						    _LWP_UNPARK(2)

NAME
_lwp_unpark -- resume execution of a waiting LWP LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <lwp.h> int _lwp_unpark(lwpid_t lwp, const void *hint); DESCRIPTION
_lwp_unpark() resumes execution of the light-weight process lwp. The target LWP is assumed to be waiting in the kernel as a result of a call to _lwp_park(). If the target LWP is not currently waiting, it will return immediately upon the next call to _lwp_park(). See _lwp_park(2) for a description of the hint argument. RETURN VALUES
A 0 value indicates that the call succeeded. A -1 return value indicates an error occurred and errno is set to indicate the reason. ERRORS
[ESRCH] No LWP can be found in the current process corresponding to that specified by lwp. SEE ALSO
_lwp_park(2), _lwp_unpark_all(2), _lwp_wakeup(2) HISTORY
The _lwp_unpark() system call first appeared in NetBSD 5.0. BSD

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(). BSD
