dso__data_close(9)

💅 dso__data_close — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual and it's honestly so short it's giving "I woke up, closed a file descriptor, and went back to bed" energy. but we're gonna give it the main character treatment it deserves 🎀

🌸 NAME

dso__data_close — close the DSO data file, periodt 💅

---

✨ SYNOPSIS

void dso__data_close (struct dso *dso );

that's it. that's the whole vibe. no return value, no drama, no notes 🔥

---

🦋 ARGUMENTS

• dso — the dso object, bestie. that's the whole argument. that's the whole girl. she's the one getting her data file closed 🫶

---

💖 DESCRIPTION

okay so listen 👑 this is the external interface for closing the dso's data file descriptor. like, the official, out-in-public, "yes you may call me" way to do it. not me being the designated file-closer of the group chat 😭

so if you've got a struct dso * and you're done with its data file descriptor, this is the function you call. she closes it. respectfully. slay.
