* For connectionless sockets, the destination `port` and `address` must be | |
* specified. Connected sockets, on the other hand, will use their associated | |
* remote endpoint, so the `port` and `address` arguments must not be set. | |
* | |
* The `msg` argument contains the message to be sent. | |
* Depending on its type, different behavior can apply. If `msg` is a `Buffer`, | |
* any `TypedArray` or a `DataView`, | |
* the `offset` and `length` specify the offset within the `Buffer` where the | |
* message begins and the number of bytes in the message, respectively. | |
* If `msg` is a `String`, then it is automatically converted to a `Buffer`with `'utf8'` encoding. With messages that | |
* contain multi-byte characters, `offset` and `length` will be calculated with | |
* respect to `byte length` and not the character position. | |
* If `msg` is an array, `offset` and `length` must not be specified. | |
* | |
* The `address` argument is a string. If the value of `address` is a host name, | |
* DNS will be used to resolve the address of the host. If `address` is not | |
* provided or otherwise nullish, `'127.0.0.1'` (for `udp4` sockets) or `'::1'`(for `udp6` sockets) will be used by default. | |
* | |
* If the socket has not been previously bound with a call to `bind`, the socket | |
* is assigned a random port number and is bound to the "all interfaces" address | |
* (`'0.0.0.0'` for `udp4` sockets, `'::0'` for `udp6` sockets.) | |
* | |
* An optional `callback` function may be specified to as a way of reporting | |
* DNS errors or for determining when it is safe to reuse the `buf` object. | |
* DNS lookups delay the time to send for at least one tick of the | |
* Node.js event loop. | |
* | |
* The only way to know for sure that the datagram has been sent is by using a`callback`. If an error occurs and a `callback` is given, the error will be | |
* passed as the first argument to the `callback`. If a `callback` is not given, | |
* the error is emitted as an `'error'` event on the `socket` object. | |
* | |
* Offset and length are optional but both _must_ be set if either are used. | |
* They are supported only when the first argument is a `Buffer`, a `TypedArray`, | |
* or a `DataView`. | |
* | |
* This method throws `ERR_SOCKET_BAD_PORT` if called on an unbound socket. | |
* | |
* Example of sending a UDP packet to a port on `localhost`; | |
* | |
* ```js | |
* import dgram from 'node:dgram'; | |
* import { Buffer } from 'node:buffer'; | |
* | |
* const message = Buffer.from('Some bytes'); | |
* const client = dgram.createSocket('udp4'); | |
* client.send(message, 41234, 'localhost', (err) => { | |
* client.close(); | |
* }); | |
* ``` | |
* | |
* Example of sending a UDP packet composed of multiple buffers to a port on`127.0.0.1`; | |
* | |
* ```js | |
* import dgram from 'node:dgram'; | |
* import { Buffer } from 'node:buffer'; | |
* | |
* const buf1 = Buffer.from('Some '); | |
* const buf2 = Buffer.from('bytes'); | |
* const client = dgram.createSocket('udp4'); | |
* client.send([buf1, buf2], 41234, (err) => { | |
* client.close(); | |
* }); | |
* ``` | |
* | |
* Sending multiple buffers might be faster or slower depending on the | |
* application and operating system. Run benchmarks to | |
* determine the optimal strategy on a case-by-case basis. Generally speaking, | |
* however, sending multiple buffers is faster. | |
* | |
* Example of sending a UDP packet using a socket connected to a port on`localhost`: | |
* | |
* ```js | |
* import dgram from 'node:dgram'; | |
* import { Buffer } from 'node:buffer'; | |
* | |
* const message = Buffer.from('Some bytes'); | |
