binder_cleanup_transaction(9)

💖 binder_cleanup_transaction(9) 💖

okay bestie, welcome to the Kernel API Manual page for binder_cleanup_transaction(9). This one cleans up undelivered transaction — short, iconic, no cap. 💅

🌸 NAME 🌸

binder_cleanup_transaction — cleans up undelivered transaction.

✨ SYNOPSIS ✨

here's the signature, literally exactly:

void binder_cleanup_transaction (struct binder_transaction *t , const
       char *reason , uint32_t error_code );

it returns void, so don't go looking for a return value, bestie. 🫶

🎀 ARGUMENTS 🎀

okay so here's the whole cast, three args and they all matter:

• t — transaction that needs to be cleaned up. like, the actual transaction, bestie.
• reason — reason the transaction wasn't delivered. spill the why.
• error_code — error to return to caller (if synchronous call). keep the parenthetical, it's important.
