Write data to the server.
object.Write( Buffer, [Length] )
- A buffer variable that contains the data to be written to the
server. If the variable is a String type, then the data will be written
as a string of characters. This is the most appropriate data type
to use if the server expects text data that consists of
printable characters. If the server is expecting binary data,
it is recommended that a Byte array be used instead.
- A numeric value which specifies the number of bytes to
write. Its maximum value is 231-1 = 2147483647. If a
value is specified for this argument and it is greater than the
actual size of the buffer, then the Length argument will be
ignored and the entire contents of the buffer will be written. If
the argument is omitted, then the maximum number of bytes to write
is determined by the size of the buffer.
This method returns the number of bytes actually written to the
server, or -1 if an error was encountered.
The Write method sends the data in buffer to the
server. If the connection is buffered, as is typically the case,
the data is copied to the send buffer and control immediately returns
to the program. If the control is blocking, the application will wait
until the data can be sent. If the control is non-blocking and the
write fails because it could not send all of the data to the server,
the OnWrite event will be fired when the server can accept
If the data contains binary characters, particularly
non-printable control characters and embedded nulls, you should
always provide a Byte array to the Write
method. When you provide a String variable as
the buffer, the control will process the data as text. If the
string contains Unicode characters, it will automatically be converted
to UTF-8 (8-bit) encoded text prior to being written. Using a byte
array ensures that binary data will be sent as-is without being encoded.
