_LWP_WAKEUP(2)            NetBSD System Calls Manual            _LWP_WAKEUP(2)


NAME

     _lwp_wakeup -- make a blocked light-weight process runnable


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <lwp.h>

     int
     _lwp_wakeup(lwpid_t lwp);


DESCRIPTION

     _lwp_wakeup() makes a blocked LWP runnable.  The blocked LWP must be in
     LSSLEEP state.  Unblocking the LWP does not guarantee that it will make
     progress; it may block again as soon as it resumes execution in the ker-
     nel.


RETURN VALUES


ERRORS

     _lwp_wakeup() will fail if:

     [ESRCH]            No LWP can be found in the current process correspond-
                        ing to that specified by lwp.

     [ENODEV]           The specified LWP is not in LSSLEEP state.

     [EBUSY]            The specified LWP is blocked in an uninterruptible
                        sleep.


HISTORY

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