🌸 NAME 🌸

rio_del_mport_pw_handler — removes a port-write message handler from the list of mport specific pw handlers. That's the whole vibe: handler goes bye-bye from the mport-specific pw handler list. 💅

✨ SYNOPSIS ✨

here's the signature, character-for-character, no cap:

int rio_del_mport_pw_handler (struct rio_mport *mport , void *context ,
       int (*pwcback)(struct rio_mport *mport, void *context, union rio_pw_msg
       *msg, int step) );

---

🎀 ARGUMENTS 🎀

• mport — the RIO master port to bind the portwrite callback. yes bestie, that's what it says.
• context — the registered handler specific context to pass on event.
• pwcback — the registered callback function. its full signature is the int (*pwcback)(...) situation up in the synopsis, iykyk. 🦋

---

💅 DESCRIPTION 💅

Returns 0 if the request has been satisfied. that's the return contract, fr fr — request satisfied? 0. periodt. 🫶
