Macro Definition Documentation

◆ SMQTTE_ALREADYCON

#define SMQTTE_ALREADYCON -10006

Calling SharkMQ_connect when a connection is already established.

◆ SMQTTE_CONREFUSED

#define SMQTTE_CONREFUSED -10007

Broker refused the connection request.

See SharkMQTT_connackCode for details.

◆ SMQTTE_ERRORBASE

#define SMQTTE_ERRORBASE -10000

This code is not used.

The code is the base for error codes returned by SharkMQ.

◆ SMQTTE_NOMEM

#define SMQTTE_NOMEM -10009

A pending QoS operation could not be stored.

◆ SMQTTE_OVERFLOW

#define SMQTTE_OVERFLOW -10005

The SharkSSL output buffer is not sufficiently large for the operation you are attempting.

Increase the buffer size.

◆ SMQTTE_PONGTIMEOUT

#define SMQTTE_PONGTIMEOUT -10002

The client sent a PING to the broker but did not receive a PONG response.

◆ SMQTTE_PROTOCOL_ERROR

#define SMQTTE_PROTOCOL_ERROR -10003

Something's wrong.

◆ SMQTTE_SERVERNOTTRUSTED

#define SMQTTE_SERVERNOTTRUSTED -10008

Returned by SharkMQTT_connect if the MQTT broker is not trusted.

SharkMQTT_connect calls seSec_handshake and expects the return value from this function to be SharkSslConTrust_CertCnDate if the code is compiled with the flag SHARKSSL_CHECK_DATE=1 and the return value to be SharkSslConTrust_CertCn if compiled without this flag set.

◆ SMQTTE_SOCKET

#define SMQTTE_SOCKET -1

Error codes received from the TCP/IP stack are sent "as is".

These error codes have a value greater than SMQTTE_ERRORBASE.

◆ SMQTTE_TIMEOUT

#define SMQTTE_TIMEOUT -10001

Similar to SMQTT_TIMEOUT, but returned when a timeout was not expected.
