TCPClient

getWriteError()

Get the error code of the most recent write() operation.

Returns: int 0 when everything is ok, a non-zero error code in case of an error.

This value is updated every after every call to #write--4 or can be manually cleared by clearWriteError().

// SYNTAX
int err = client.getWriteError();

// EXAMPLE
TCPClient client;
// Write in non-blocking mode
int bytes = client.write(buf, len, 0);
int err = client.getWriteError();
if (err != 0) {
  Log.trace("TCPClient::write() failed (error = %d), number of bytes written: %d", err, bytes);
}
