TLM extension

Recommended Posts

I read some source code.

class TlmExtension : public tlm_extension<TlmExtension>
void setExtension(tlm::tlm_generic_payload &in, tlm::tlm_generic_payload &out)
    TlmExtension *input  = (TlmExtension *)0;
    TlmExtension *output = new TlmExtension;
    if (input != NULL) {


I think above code is wrong. Because of when exit  setExtension  function. We cant delete object create by new operator (output )

How to resolve this problem?  Thanks.

Actually this is done in the desrtuctor of the tlm_generic_payload. This part calls for all extensions the free() function. So if out is handled properly destroyed all extensions are destroyed as well. The other option is to call free_all_extensions() explicitly which also calls free() for all extensions as well as for auto extensions (those might be registered when a memory manager for the generic payload is used, usually in AT style modelling using the non-blocking interfaces).
