CmpTlsRead (FUN) ¶ FUNCTION CmpTlsRead : __XINT Receive data from the encrypted channel. If the connection is not established yet, this will be done transparent in the background. Normally only data is of the encrypted channel is consumed. In some cases (Handshaking has not finished or renegotiation of the session keys) this function will also write data. If the unterlaying IO doens’t write automatically the need to send data will be indicated using the corresponding error code. InOut: Scope Name Type Comment Return CmpTlsRead __XINT Number of bytes received. 0 if an error occured. Input hTlsConn RTS_IEC_HANDLE Handle of the TLS connection, created with one of the TLSxxxOpen functions pbyBuffer POINTER TO BYTE Pointer to a databuffer, where the received decrypted data should be written to. xiBufferSize __XINT Size of pbyData. Maximum number of bytes, that could be received from the TLS connection. pResult POINTER TO RTS_IEC_RESULT Result OF THIS operation. May be one OF these values: ERR_OK: No error. Everything worked as expected. ERR_NOTINITIALIZED: The TLS component was not initialized proberly. ERR_TLS_CONNECTION_CLOSED: The TLS connection is closed. Use TlsShutdown to shutdown locally. ERR_TLS_WANT_READ: The operation needs TO read data FROM the IO system. There is no data available. ERR_TLS_WANT_WRITE: The operation needs to write data to the IO system. This is not possible. ERR_TLS_RETRY_OPERATION: Something went wrong. Try the same function call again ERR_TLS_IO_SYSTEM: An error in the unterlaying IO system. ERR_TLS_INTERNAL: An internal Error of the TLS Component ERR_FAILED: Unknown error.

CmpTlsShutdown (FUN) ¶ FUNCTION CmpTlsShutdown : RTS_IEC_RESULT There are two ways to shutdown the TLS connection: bidirectional: The first call of TlsShutdown will send the shutdown message. The operation will return ERR_TLS_RETRY_OPERATION. Then the function has to be called again. If the acknowledge of the peer was received ERR_OK will be returned. If the acknowledge was not received yet the function will return ERR_TLS_WANT_READ. unidirectional: The first call of TlsShutdown will send the shutdown message. The operation will return ERR_TLS_RETRY_OPERATION. Close the IO channel and clean up. Don’t wait for the acknowledge of the peer. InOut: Scope Name Type Comment Return CmpTlsShutdown RTS_IEC_RESULT Result of this operation. May be one of these values: ERR_OK: No error. Everything worked as expected. ERR_NOTINITIALIZED: The TLS component was not initialized proberly. ERR_TLS_CONNECTION_CLOSED: The TLS connection is closed. ERR_TLS_WANT_READ: The operation needs TO read data FROM the IO system. There is no data available. ERR_TLS_WANT_WRITE: The operation needs to write data to the IO system. This is not possible. ERR_TLS_RETRY_OPERATION: Something went wrong. Try the same function call again ERR_TLS_IO_SYSTEM: An error in the unterlaying IO system. ERR_TLS_INTERNAL: An internal Error of the TLS Component ERR_FAILED: Unknown error. Input hTlsConn RTS_IEC_HANDLE Handle of the TLS connection, created with one of the TLSxxxOpen functions

CmpTlsWrite (FUN) ¶ FUNCTION CmpTlsWrite : __XINT Send data over the encrypted channel. If the connection is not established yet, this will be done transparent in the background. Normally only data is written to the unterlaying IO. In some cases data have to be read (Handshaking has not finished or renegotiation of the session keys). If not data is for reading is available this will be indicated through the corresponding error code. InOut: Scope Name Type Comment Return CmpTlsWrite __XINT Number of bytes sent. 0 if an error occured. Input hTlsConn RTS_IEC_HANDLE Handle of the TLS connection, created with one of the TLSxxxOpen functions pbyData POINTER TO BYTE Pointer to data, that should be sent over the TLS connection xiDataSize __XINT Size of pbyData. Number of bytes that should be sent over the TLS connection pResult POINTER TO RTS_IEC_RESULT Result OF THIS operation. May be one OF these values: ERR_OK: No error. Everything worked as expected. ERR_NOTINITIALIZED: The TLS component was not initialized proberly. ERR_TLS_CONNECTION_CLOSED: The TLS connection is closed. Use TlsShutdown to shutdown locally. ERR_TLS_WANT_READ: The operation needs TO read data FROM the IO system. There is no data available. ERR_TLS_WANT_WRITE: The operation needs to write data to the IO system. This is not possible. ERR_TLS_RETRY_OPERATION: Something went wrong. Try the same function call again ERR_TLS_IO_SYSTEM: An error in the unterlaying IO system. ERR_TLS_INTERNAL: An internal Error of the TLS Component ERR_FAILED: Unknown error.
