fdt_get_alias_namelen(9) — Kernel API Manual 💅

okay so bestie, welcome to the Kernel API Manual page for fdt_get_alias_namelen(9). it's a libfdt moment and we're gonna get through it together, no skipping ✨

🎀 NAME 🎀

fdt_get_alias_namelen — get alias based on substring 🫶

✨ SYNOPSIS ✨

const char * fdt_get_alias_namelen (const void *fdt , const char *name ,
       int namelen );

🌸 ARGUMENTS 🌸

• fdt — pointer to the device tree blob. literally the blob, bestie 🫶
• name — name of the alias to look up. the alias in question 🎀
• namelen — number of characters of name to consider. only this many chars get the vibe check 💅

💖 DESCRIPTION 💖

Identical to fdt_get_alias, but only examine the first namelen characters of name for matching the alias name. no cap, that's the whole twist: it's the substring edition 💅

🔥 RETURN 🔥

a pointer to the expansion of the alias named name, if it exists, NULL otherwise. so if it's there you get the pointer, and if it's not you get NULL. periodt 😭
