parse_one_key_value_pair(9)

okay so bestie, welcome to the parse_one_key_value_pair(9) page from the Kernel API Manual 💖 we folded the manual name in right here so you don’t have to stare at a duplicated header line. This function is literally here to parse one key/value pair and update the config, and it’s giving tiny-but-iconic utility energy. Slay.

🎀 NAME 🎀

parse_one_key_value_pair — parses one key/value pair and updates the configuration data structure. One pair, one update, no cap. 💅

✨ SYNOPSIS ✨

int parse_one_key_value_pair (const char *key , const char *value ,
       struct device_config *config );

🫶 ARGUMENTS 🫶

• key — the optional key name. Optional! We love a flexible bestie.
• value — the optional value. Also optional, fr fr.
• config — the configuration data that’s going to be updated.

🌈 RETURN 🌈

It returns VDO_SUCCESS or an error. That’s the whole vibe check: success or nope. 😭
