ccw_device_tm_start_timeout(9) 💖

okay so bestie, we're deep in the Kernel API Manual and this page is literally about ccw_device_tm_start_timeout — the start-function girlie. no cap, she's here to start a tcw and dip. ✨

✨ NAME ✨

ccw_device_tm_start_timeout — perform start function. that's the assignment, periodt. 💅

🎀 SYNOPSIS 🎀

int ccw_device_tm_start_timeout (struct ccw_device *cdev , struct tcw *tcw , unsigned long intparm , u8 lpm , int expires );

💅 ARGUMENTS 💅

  • cdev — the ccw device on which to perform the start function. she's the main character device, obvi.
  • tcw — the transport-command word to be started. go little command word, go 🦋
  • intparm — user defined parameter to be passed to the interrupt handler. it's giving "custom little note for the interrupt handler."
  • lpm — mask of paths to use. path selection vibes, iykyk.
  • expires — time span in jiffies after which to abort request. so lowkey a deadline in jiffies; after that, abort request 😭

🦋 DESCRIPTION 🦋

Start the tcw on the given ccw device. Return zero on success, non-zero otherwise. that's the whole plot — zero means slay, non-zero means not slay. 💀
