memtostr_pad(9)

okay so this is memtostr_pad(9), straight out of the Kernel API Manual — and yes, she’s here to copy a possibly non-NUL-term string into a NUL-term string with NUL padding in the destination 💅✨

🌸 NAME 🌸

memtostr_pad — copy a possibly non-NUL-term string to a NUL-term string with NUL padding in the destination 🎀

✨ SYNOPSIS ✨

memtostr_pad (dest , src );

🎀 ARGUMENTS 🎀

• dest — pointer to destination NUL-terminates string 😭 (yes bestie, that’s the wording — keep it moving)
• src — pointer to character array (likely marked as __nonstring) 🫶

💅 DESCRIPTION 💅

This is a replacement for strncpy uses where the source is not a NUL-terminated string. No cap, that’s literally the whole point of her 💖

Important, bestie: sizes of dest and src must be known at compile-time. Not runtime, not vibes — compile-time. Periodt ⭐
