dpcon_open(9)

🌸 NAME 🌸

dpcon_open(9) — from the Kernel API Manual, bestie — opens a control session for the specified object. That's the assignment, and it ate. 💅✨

✨ SYNOPSIS ✨

int dpcon_open (struct fsl_mc_io *mc_io , u32 cmd_flags , int dpcon_id ,
       u16 *token );

🎀 ARGUMENTS 🎀

• mc_io — Pointer to MC portal's I/O object. Your portal bestie. 🫶
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Pick your flags, but it's gotta be one or more. 🌈
• dpcon_id — DPCON unique ID. The one and only. 👑
• token — Returned token; use in subsequent API calls. Keep it close — it's giving VIP pass. 🎟️

🦋 DESCRIPTION 🦋

Okay so this function can be used to open a control session for an already created object. The object may have been declared in the DPL, or it may have been made by calling the dpcon_create function — either way, we're opening that session, no cap. ✨

Then it returns a unique authentication token. That token is associated with the specific object ID and the specific MC portal, so it's not just a random little string — it's literally tied to that object + that portal. You must use this token in all subsequent commands for this specific object. Main character token energy, fr fr. 🔥

💀 RETURN 💀

This section is literally empty — no return-value details are listed here, periodt. Not me pointing at an empty section and calling it iconic, but here we are. 😭
