How to trigger a notification based on an action of an RPC ?

[anasov]

Dear Community , I hope you are all doing well,

I'm fairly new to everything Netconf/yang and I'm trying to implement a SIL for an equipment. So I started reading and analyzing the .c file of the toaster model , in order to understand the code so that I can create my own afterwards. One issue that I found with the toaster.c code is that the rpc "make_toast" was not linked to the notification "toastDone" . So I don't understand , why when the timer expire , the notification is triggered. Can someone please unlighten me on this point ?

Another question that I have , is that I don't understand what "LOGDEBUG" does or mean , in addition to various other expressions such as :
ERR_NCX_IN_USE, or ERR_NCX_RESOURCE_DENIED
I would be very grateful if someone can guide me to a link where I can understand all of it .

Thanks in advance ,
