strip_whitespace(9)

💖 NAME 💖

okay so bestie, say hi to strip_whitespace(9) from the Kernel API Manual 💖. Its whole thing is: strip_whitespace — Strip and pad trailing whitespace. That's the name line, no cap. And yes, the NAME says “pad” while the DESCRIPTION later talks about stripping all trailing whitespace and NUL terminating — both are in the original, I'm just reporting the lore. 👀

---

✨ SYNOPSIS ✨

the signature, exactly as written, no edits:

void strip_whitespace (int i , char *buf );

---

🎀 ARGUMENTS 🎀

two args, two lil icons:

• i — size of buffer
• buf — string to modify

---

🦋 DESCRIPTION 🦋

okay so the actual behavior, as stated: This function will strip all trailing whitespace and NUL terminate the string. That's it. It strips all trailing whitespace and NUL terminates the string. no extra drama, just clean strings and a NUL at the end 💅.
