STRUCT SSAM_RESPONSE(9)

💅 struct ssam_response(9) 💅

okay bestie, welcome to the Kernel API Manual entry for struct ssam_response — literally the response buffer for a SAM request. it's giving "the place where the reply data pulls up" energy, and honestly? iconic. 🦋

🎀 NAME 🎀

struct ssam_response — response buffer for SAM request. periodt.

✨ SYNOPSIS ✨

       struct ssam_response {
           size_t capacity;
           size_t length;
           u8 *pointer;
        };

🌸 Members 🌸

• capacity — capacity of the buffer, in bytes. that's the size vibe.
• length — length of the actual data stored in the memory pointed to by pointer, in bytes. Set by the transport system. not you, bestie — the transport system handles that one.
• pointer — pointer to the buffer's memory, storing the response payload data. this is where the payload actually lives.
