dpni_open(9)

🌸 NAME 🌸

okay so bestie, this page is dpni_open(9) from the Kernel API Manual — and it’s literally “open a control session for the specified object.” main character energy for your MC portal, no cap 💅✨

---

🦋 SYNOPSIS 🦋

int dpni_open (struct fsl_mc_io *mc_io , u32 cmd_flags , int dpni_id ,
       u16 *token );

---

🎀 ARGUMENTS 🎀

• mc_io — pointer to the MC portal’s I/O object, your little entry pass to the portal 🫶
• cmd_flags — command flags, bestie: one or more of 'MC_CMD_FLAG_' ⭐
• dpni_id — the DPNI unique ID 👑
• token — the returned token; use it in subsequent API calls 🔑

---

💖 DESCRIPTION 💖

This function can be used to open a control session for an already created object; an object may have been declared in the DPL or by calling the dpni_create function. 🧚

This function returns a unique authentication token, associated with the specific object ID and the specific MC portal; this token must be used in all subsequent commands for this specific object. So like… keep track of it, okay? It’s giving “VIP wristband for exactly one object at exactly one portal” 💀🎀
