Field Documentation

ctor

void(* CnLoadVt::ctor)(CnLoad *, va_list)

Constructor callback for the message.

Should allocate additional memory for the message, if needed (see "indirect context") and initialize the message - read arguments from the va_list and fill the load passed through the CnLoad pointer.

Note

The input va_list will hold all values passed to cn_publish() after the CnChannel argument.

dtor

void(* CnLoadVt::dtor)(CnLoad *)

Destructor callback for the message.

Should free all the memory allocated by the CnLoadVt::ctor.

size

(

)

Callback for obtaining the size of the load.

Should return the size of the load in bytes.
