netlbl_catmap_setlong(9)

🦋 netlbl_catmap_setlong(9) 🦋

okay bestie, you're looking at the Kernel API Manual page for netlbl_catmap_setlong(9) — yes, the whole page, and we're gonna get through it together 💅✨

🌸 NAME 🌸

netlbl_catmap_setlong — import an unsigned long bitmap 🫶

✨ SYNOPSIS ✨

here's the signature, bestie — do not let the types scare you:

int netlbl_catmap_setlong (struct netlbl_lsm_catmap **catmap , u32
       offset , unsigned long bitmap , gfp_t flags );

🎀 ARGUMENTS 🎀

• catmap — pointer to the category bitmap, like the map you're importing into 🗺️
• offset — offset to the start of the imported bitmap, so it knows where the import starts 📍
• bitmap — the bitmap to import, literally the thing being brought in 🧺
• flags — memory allocation flags, the little settings for allocation 🚩

💖 DESCRIPTION 💖

okay so netlbl_catmap_setlong() imports the bitmap specified in bitmap into catmap, using the offset in offset. The offset must be aligned to an unsigned long — that's a hard requirement, not a vibe suggestion 😭. It returns zero on success and negative values on failure. Periodt. ✅
