Supplementary explanation

• When this API is run multiple times, the callback method specified later takes effect.
• If nil is specified in delegate when calling this API, the registered callback method is canceled.
• It takes about 30 seconds for the disconnection event to occur after the disconnection.
• Do not make any call operation when EPOS2_EVENT_RECONNECTING has occurred.
  Wait until EPOS2_EVENT_RECONNECT or EPOS2_EVENT_DISCONNECT occurs.
• EPOS2_EVENT_DISCONNECT occurs in the following cases:
  When disconnect is running
  When connection fails after occurrence of EPOS2_EVENT_RECONNECTING
• When EPOS2_EVENT_DISCONNECT occurs, it is not necessary to call disconnect.
  When disconnect is called, ERR_ILLEGAL will be returned in the return value.
