bitmap_parselist_user(9)

okay so welcome to the Kernel API Manual, bestie 💖 — today’s main character is bitmap_parselist_user, and she is here to convert user buffer’s list format ASCII string to bitmap. periodt. ✨

🎀 NAME 🎀

bitmap_parselist_user — convert user buffer’s list format ASCII string to bitmap.

🌸 SYNOPSIS 🌸

int bitmap_parselist_user (const char __user *ubuf , unsigned int ulen , unsigned long *maskp , int nmaskbits );

🦋 ARGUMENTS 🦋

• ubuf — pointer to user buffer containing string. 🫶
• ulen — buffer size in bytes. If string is smaller than this then it must be terminated with a . (yes bestie, that gap is in the original — don’t come for me 🙈)
• maskp — pointer to bitmap array that will contain result. 💅
• nmaskbits — size of bitmap, in bits. 🔥

💜 DESCRIPTION 💜

Wrapper for bitmap_parselist, providing it with user buffer. That’s the whole vibe — she’s a tiny handoff queen. 👑
