✨ dpio_open(9) ✨

okay bestie, welcome to the dpio_open glow-up 💅 this one lives in the Kernel API Manual, and honestly? she's giving "backstage pass to the DPIO club" energy 🎀

---

🌸 NAME 🌸

dpio_open — open a control session for the specified object 🫶

---

⭐ SYNOPSIS ⭐

int dpio_open (struct fsl_mc_io *mc_io , u32 cmd_flags , int dpio_id ,
u16 *token );

like yes that's the whole signature, no cap 🧚

---

💖 ARGUMENTS 💖

• mc_io — pointer to the MC portal's I/O object 🌈
• cmd_flags — command flags; one or more of 'MC_CMD_FLAG_' 👑
• dpio_id — the DPIO unique ID, her literal government name 🪪
• token — the returned token; you use this in subsequent API calls 🔑

---

🦋 DESCRIPTION 🦋

so this function is how you open a control session for an already created object 💫 and yes, "already created" is the whole vibe — the object may have been declared in the DPL, or it may have been made by calling the dpio_create function 🫧

this function returns a unique authentication token, and that token is associated with the specific object ID and the specific MC portal 🔥 this token must be used in all subsequent commands for this specific object — like she's your VIP wristband and you are NOT getting back in without her 💅

---

💀 RETURN 💀

this section is literally empty in the original, bestie 😭 no return value written, no nothing — so we're not inventing one, we're just respectfully leaving the space empty 🙈
