hl_mmap_mem_buf_get(9)

💖 NAME 💖

okay so bestie, this is hl_mmap_mem_buf_get(9) from the Kernel API Manual — it increases the buffer refcount and returns a pointer to the buffer descriptor. no cap, that's the whole vibe. 💅

✨ SYNOPSIS ✨

struct hl_mmap_mem_buf * hl_mmap_mem_buf_get (struct hl_mem_mgr *mmg , u64 handle );

🎀 ARGUMENTS 🎀

• mmg — parent unified memory manager. literally the parent unified memory manager, okay? 👑
• handle — requested buffer handle. the one and only requested buffer handle, periodt. 🎀

🦋 DESCRIPTION 🦋

So the vibe check is: find the buffer in the store 🕵️‍♀️, return a pointer to its descriptor, and increase the buffer refcount. if it's not found — return NULL. that's it, that's the function. 💀✨
