	char * teldSendBufPtr,
	int teldBytes,
	int flag
	);

Function Description

This function is called to give data to the TELNET server to send it to the TELNET client.

Flag Values

If the 'flag' value is TM_TELD_SEND_EOL, it indicates that end of command has been reached and means that the telnet server needs to append <CR, LF> in ASCII mode, or <IAC, EOR> in binary mode to the user data. If the 'flag' value is TM_TELD_SEND_COMMAND, it indicates that the user is sending a TELNET IAC command, and that the Treck TELNET server should treat the data as a command, and not map the IAC character.

Flow Control

If the Treck server does not have enough room for the data, it will not copy the data and return TM_EWOULBLOCK. The caller should try and re-send the data at a later time.

Parameters

• teldHandle

  Unique identifier for a TELNET connection.

• teldSendBufPtr

  A pointer to the user send buffer containing the data.

• teldBytes

  The number of bytes in 'teldSendBufPtr' to be sent.

• flag

  One of the following:

• TM_TELD_SEND_EOL: indicates that an EOL should be sent.
• TM_TELD_SEND_COMMAND: indicates that the user is sending a TELNET IAC command instead of data.
• TM_TELD_SEND_DONT_FLUSH: instruct the telnet server to buffer the user data instead of sending it immediately. This flag should only be used if the user expects to send more data.

Returns

• TM_ENOERROR

  Success.

• TM_ENOBUFS

  Failed to allocate a buffer to copy the send data into.

• TM_EINVAL

  Invalid Telnet Handle.

• TM_EWOULDBLOCK

  User did not have enough room for all the data.
