🌸 NAME 🌸

netlbl_catmap_setrng — literally sets a range of bits in a LSM secattr catmap. that's it. that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

int netlbl_catmap_setrng (struct netlbl_lsm_catmap **catmap , u32 start
, u32 end , gfp_t flags );

yes the line break in the middle of the parameter list is real, don't come for me, that's just how the page looks 😭

🎀 ARGUMENTS 🎀

  • catmap — a pointer to the category bitmap 🗺️ like, the actual map you're decorating with bits.
  • start — the starting bit ⭐ where the range begins.
  • end — the last bit in the string 🏁 the range goes up to and includes this one, no cap.
  • flags — memory allocation flags 🌈 the usual gfp_t situation, passed along for any memory the call needs.

💖 DESCRIPTION 💖

So the whole job here? Set a range of bits, starting at start and ending with end. inclusive range behaviour, main character energy, start through end both invited to the party 🎉.

Returns zero on success — iconique, we love a clean 0 ✨ — and negative values on failure 😭 so always check your return value, bestie, fr fr.
