✨ NAME ✨

xe_migrate_alloc — allocates a migrate struct for a given &xe_tile 💅

🦋 SYNOPSIS 🦋

struct xe_migrate * xe_migrate_alloc (struct xe_tile *tile );

🌸 ARGUMENTS 🌸

• tile — the xe_tile you're handing over. that's it, that's the whole argument, she's lowkey simple 🫶

🧚 DESCRIPTION 🧚

so what does it do? it allocates a xe_migrate for a given tile. that's the tea, no cap ☕✨ you give it a tile, it sets you up with a migrate struct for that tile. main character energy for a one-liner, honestly 👑

⭐ RETURN ⭐

• you get an xe_migrate back on success — slay 💖
• or NULL when it's out of memory 😭 (yes, that's the fail case, no cap, watch for it)

ngl bestie, the only real gotcha here is the NULL return — if you're out of memory you get NULL, not a struct, so check it before you go dereferencing like a menace 💀
