Re: [sr-dev] rpc: inter module rpc printf callback structure

Hello Andrei, Thanks for getting back to me on this one. Here's a pseudocode example. Let's assume that we have module a and module b. We have an rpc call into module a to print out some info. Module b has some relevant info that we would like to print out during the rpc call into module a. inside module a we have: static void module_a_print_info(rpc_t *rpc, void *c) { /*declare a variable to pass rpc stuf up to module b */ rpc_cb_ctx_t *rpc_cb; /* print stuff related to module a */ rpc->printf(c, "module a stuff ...."); /*let's print stuf from mudule b now via a callback */ rpc_cb->rpc = rpc; rpc_cb->c = c; run_callback_into_module_b( ...., (void *)rpc_cb); } inside module b, we have the callback: void module_b_callback_function(...., struct module_b_generic_callback_param *param) /* extract rpc and c via the generic module_b_generic_callback_param */ rpc_cb_ctx_t* rpc_cb = (rpc_cb_ctx_t*)(param); rpc_t *rpc = rpc_cb->rpc; void *c = rpc_cb->c; rpc->printf(c, "module b stuff ...."); } Hope that the above pseudocode explains what I want to achieve. There is no impact on the core, all I want is to declare the rpc_cb_ctx_t structure into the rpc.h in order to make it available in an atomic way to both module a and b.

The real modules are: - module a: modules_k/dialog (dialog.c:internal_rpc_print_dlg) - module b: modules_k/qos (qos_handlers.c:qos_dialog_rpc_context_CB)
