Add UV_UDP_REUSEADDR flag instead, which can be passed to uv_udp_bind.
If the udp handle is unbound when uv_udp_set_memberhsip or
uv_udp_set_multicast_interface is called, the handle will be bound with
UV_UDP_REUSEADDR set.
Introduce `int uv_pipe_pending_count(uv_pipe_t*)` and
`uv_handle_type uv_pipe_pending_type(uv_pipe_t*)`. They should be
used in IPC pipe's read cb to accept incoming handles:
int count = uv_pipe_pending_count(pipe);
int i;
for (i = 0; i < count; i++) {
uv_handle_type type = uv_pipe_pending_type(pipe);
/* ... */
uv_accept(...);
}
When the supplied buffer is not big enough and UV_ENOBUFS is
returned, hint the user about the required size by setting
the len paramemeter to the required value.
Applies to:
- uv_pipe_getsockname
- uv_fs_event_getpath
- uv_fs_poll_getpath
This improves API consistency with uv_read and uv_write and may
improve efficiency for some uses. Vectored IO is emulated when the
requisite system calls are unavailable.
These functions supersede uv_loop_new and uv_loop_delete.
uv_loop_init initialized a user allocated loop and uv_loop_close
removes all associated resources a loop uses after it has finished
execution.
uv_loop_new and uv_loop_delete are now deprecated.

Signals don't exist on Windows, but libuv emulates the behaviour of
several Unix signals. This wasn't documented, and the existing
documentation for signal reception emulation on Windows was worded as if
it applied to signal sending, which it does not.
If multiple handles arrive to the IPC pipe at the same time (happens on
some platforms), libuv will queue them internally, and call `read2_cb`
multiple times with a null-buffer and proper `handle_type`.
Useful to know when the the event loop is empty, this can't be done with
uv_run() without possibly blocking, or running some events (which might
empty the event loop as a side-effect).
`uv_try_write(stream, buf, size)` acts like `uv_write()`,
but without queueing actual write until UV_POLLOUT (or IOCP completion).
This is useful for doing writes using on-stack `uv_write_t` requests.
fix#1025
If spawning a process fails due to an exec() failure (but it succeeded
in forking), then this should be considered a spawn failure instead of
an asynchronous termination of the process. This allows to check for
common exec() failure conditions such as a bad path quickly instead of
having to rely on keeping track of the async callback.
Additionally, the meaning of the two fields returned in the callback are
now exactly what they advertise to be. The process exit argument is not
one of two values depending on what happened to the child.
Fixes#978.
Document the fact that the maximum path length for UNIX domain socket
paths is much less than _POSIX_PATH_MAX.
For most file systems, _POSIX_PATH_MAX is 1024 or 4096 bytes while
`sizeof(sockaddr_un.sun_path)` is typically between 92 and 108 bytes.
Make it possible to call uv_tty_reset_mode() from inside a signal
handler. The primary motivation is to make it possible to restore
the TTY from inside a SIGINT or SIGTERM signal handler.
Fixes#954.
Seems to have been overlooked in the reference counting refactor back
in May 2012 in commit 9efa8b3. Clarify what "active" means for
different kinds of handles.
