_LWP_WAIT(2) BSD System Calls Manual _LWP_WAIT(2)
_lwp_wait -- wait for light-weight process termination
Standard C Library (libc, -lc)
_lwp_wait(lwpid_t wlwp, lwpid_t *rlwp);
_lwp_wait() suspends execution of the calling LWP until the LWP specified by wlwp termi-
nates. The specified LWP must not be detached. If wlwp is 0, then _lwp_wait() waits for
any undetached LWP in the current process.
If rlwp is not NULL, then it points to the location where the LWP ID of the exited LWP is
Upon successful completion, _lwp_wait() returns a value of 0. Otherwise, an error code is
returned to indicate the error.
_lwp_wait() will fail if:
[ESRCH] No undetached LWP can be found in the current process corresponding to that spec-
ified by wlwp.
[EDEADLK] The calling LWP is the only LWP in the process.
[EDEADLK] The LWP ID specified by wlwp is the LWP ID of the calling LWP.
[EINTR] _lwp_wait() was interrupted by a caught signal, or the signal did not have the
SA_RESTART flag set.
The _lwp_wait() system call first appeared in NetBSD 2.0.
