dpseci_open(9)

💅 dpseci_open(9) 💅

okay so bestie, welcome to this little corner of the Kernel API Manual. this is the page for dpseci_open, and it's literally the “open a control session for the specified object” move. 🫶

---

🌸 NAME 🌸

dpseci_open — open a control session for the specified object. slay, that's the whole name vibe. ✨

---

✨ SYNOPSIS ✨

int dpseci_open (struct fsl_mc_io *mc_io , u32 cmd_flags , int dpseci_id , u16 *token );

---

🎀 ARGUMENTS 🎀

• mc_io — pointer to the MC portal's I/O object; think of it as the portal's little handshake pass 🛂.
• cmd_flags — command flags, and you can pass one or more of 'MC_CMD_FLAG_'; yes bestie, that's the exact spelling.
• dpseci_id — the unique ID for the DPSECI object. no cap, it's how we know which one we're talking to 🔥.
• token — the returned token; keep it safe because you use it in subsequent API calls. this is your backstage pass 🎟️.

---

🦋 DESCRIPTION 🦋

so here's the tea ☕: dpseci_open opens a control session for an object that's already been created. that object might have been declared statically in the DPL, or it might have been created dynamically — either way, this function is the one that gets you a session for it. 💖

it returns a unique authentication token. that token is tied to the specific object ID and to the specific MC portal, so it's not a one-size-fits-all situation. you absolutely must use this token in all subsequent commands for this specific object. periodt. 👑

---

💀 RETURN 💀

bestie, the original page leaves this section literally empty — there are no return details listed here, so I'm not gonna invent any. 🙈
