💅 pdc_system_map_find_addrs(9) — Kernel API Manual ✨

okay bestie, this is the page for pdc_system_map_find_addrs(9) from the Kernel API Manual — title and manual name are right there, we are so back 💖.

💖 NAME 💖

pdc_system_map_find_addrs — retrieve additional address ranges. That’s literally the whole name vibe, no cap ✨.

✨ SYNOPSIS ✨

int pdc_system_map_find_addrs (struct pdc_system_map_addr_info
       *pdc_addr_info , long mod_index , long addr_index );

🎀 ARGUMENTS 🎀

• pdc_addr_info — return buffer address. (The place where the answer lands, bestie 🫶)
• mod_index — fixed address module index.
• addr_index — address range index.

🌸 DESCRIPTION 🌸

okay so the function retrieves additional information about subsequent address ranges for modules with multiple address ranges. That’s the job 💅. If a module has multiple address ranges, this is the little helper that gets you the extra deets about the subsequent address ranges — and yes, “multiple address ranges” is the key phrase, periodt 🌈.
