memcpy_and_pad(9)

💖 memcpy_and_pad(9) 💖

okay so bestie, this is the Kernel API Manual page for memcpy_and_pad(9), and we're about to make the whole copy-with-padding thing make sense. It's giving kernel-section energy and honestly? Obsessed. 💅✨

✨ NAME ✨

memcpy_and_pad — Copy one buffer to another with padding. 🎀

🦋 SYNOPSIS 🦋

void memcpy_and_pad (void *dest , size_t dest_len , const void *src ,
       size_t count , int pad );

🌸 ARGUMENTS 🌸

• dest — Where to copy to. This is the destination, aka the spot that receives the copy. 💖
• dest_len — The destination buffer size. Basically how big the destination buffer is, bestie.
• src — Where to copy from. The source, the origin, the vibe provider. ✨
• count — The number of bytes to copy. Literally that many bytes, no cap.
• pad — Character to use for padding if space is left in destination. So if there's leftover room in the destination, this is the padding character. 🫶
