STRUCT SCMI_ITERATOR_OPS(9)

🌸 NAME 🌸

struct scmi_iterator_ops — Custom iterator operations. okay so this is the Kernel API Manual page for it, and bestie it's literally the blueprint for custom iterators, no cap 💅.

✨ SYNOPSIS ✨

here's the struct exactly as it shows up — wrapped lines and all, iykyk:

       struct scmi_iterator_ops {
           void (*prepare_message)(void *message, unsigned int desc_index,
       const void *priv);
           int (*update_state)(struct scmi_iterator_state *st, const void
       *response, void *priv);
           int (*process_response)(const struct scmi_protocol_handle *ph, const
       void *response, struct scmi_iterator_state *st, void *priv);
        };

🧚 Members 🧚

• prepare_message — this operation is where you provide the custom logic to fill in the SCMI command request pointed to by message. desc_index is a reference to the next index to use in the multi-part request. go off and slay that request-filling 💖
• update_state — this operation is where you provide the custom logic to update the iterator state from the actual message response. state update era, we love to see it ✨
• process_response — this operation is where you provide the custom logic needed to process each chunk of the multi-part message. one chunk at a time, iconic behavior 🎀
