diag_trigger_mpi_show(9)

diag_trigger_mpi_show(9) — Kernel API Manual 🎀

okay bestie, gather round 🫶 this is the page for diag_trigger_mpi_show(9) — the show side of the diag_trigger_mpi attribute. It's giving kernel API manual, but make it make sense. ✨

🌸 NAME

diag_trigger_mpi_show — show the diag_trigger_mpi attribute 💅

✨ SYNOPSIS

here's the signature, copied exactly because we do not play with code:

ssize_t diag_trigger_mpi_show (struct device *cdev , struct
       device_attribute *attr , char *buf );

🎀 ARGUMENTS

• cdev — pointer to embedded class device.
• attr — ? ... yes, bestie, the original literally just says ?, and we respect the mystery 🙈
• buf — the buffer returned.

💖 DESCRIPTION

It's a sysfs 'read/write' shost attribute. That's the whole description — short, iconic, no extra lore. Periodt. 💖
