gsm_read_ea_val(9)

📦 version 7.3.1, in nixpkgs unstable

💅 gsm_read_ea_val(9) — like, the kernel API manual, but make it make sense

okay so bestie, we're in the Kernel API Manual today and the star of the show is gsm_read_ea_val — a lil function that reads a value until it hits that EA. she's short, she's sweet, she does one thing and she does it well. periodt. 🎀

✨ NAME ✨

gsm_read_ea_val — read a value until EA 🦋

✨ SYNOPSIS ✨

unsigned int gsm_read_ea_val (unsigned int *val , const u8 *data , int dlen );

like, that's the whole signature, no notes, she ate 💅

✨ ARGUMENTS ✨

  • val — the variable that's holding the value (she's getting updated, bestie, that's her whole job) 💖
  • data — a buffer of data, aka the vibes we're reading from 🌸
  • dlen — the length of data, so we know when to stop, no cap 🔥

✨ DESCRIPTION ✨

so basically: this processes an EA value. that's the whole plot. 😭

it updates the variable you passed in as val — yes, updates, she's a main character and she changes things — and then returns the processed data length. so you get two things for the price of one call, which is honestly iconic behavior 👑

ngl the description is short but she's giving efficiency. don't sleep on her.

🌈 SEE ALSO 🌈

and now, the moment you've all been waiting for, the group chat roster — aka the kernel file over at ./drivers/tty/n_gsm.c and literally every sibling function in the family 💀 (iykyk, there are a lot of them, and we're listing every single one, no skipping, we don't do that here 🫶):

like… that's the whole extended family reunion right there 😭🫶

and that's the tea, bestie 🍓 this page lives in ./drivers/tty and it's stamped October 2026 — so like, mark your calendar, she's timeless 💜 bye bestie, go read some EA values, slay ✨🧚
