read_sysfs_string(9)

🎀 NAME 🎀

okay bestie, welcome to the Kernel API Manual page for read_sysfs_string(9) 💖. This is the <pink>read_sysfs_string</pink> situation, and it is literally about reading a string from a file. Slay.

✨ SYNOPSIS ✨

Here's the signature, no cap:

int read_sysfs_string (const char *filename , const char *basedir , char
       *str );

🫶 ARGUMENTS 🫶

• filename — the name of the file to read from. That's the target, bestie 🎯
• basedir — the sysfs directory in which the file is to be found. It's giving location energy 💅
• str — output the read string. Yes, this is the output parameter, periodt ✨

💜 DESCRIPTION 💜

So what does it return? A value >= 0 on success, otherwise a negative error code. That's the whole vibe: happy non-negative success, sad negative error code 😭. No cap.
