memset_after(9)

🌸 NAME 🌸

okay so bestie, this is memset_after(9) from the Kernel API Manual — the little helper that sets a value after a struct member all the way to the end of a struct. ✨

🦋 SYNOPSIS 🦋

memset_after (obj , v , member );

🎀 ARGUMENTS 🎀

• obj — address of the target struct instance, periodt.
• v — the byte value to repeatedly write. yes, over and over 💅
• member — the struct member after which to start writing bytes.

💜 DESCRIPTION 💜

This one is good for clearing padding following the given member. That’s literally its whole thing: once you’re past that member, the padding gets cleared. 🫶

no cap, it’s giving “clean up the padding after this member” energy. 🎀
