vboxsf_create(9)

✨ vboxsf_create(9) — the kernel-side glow-up for file creation 💅

okay so bestie, welcome to the Kernel API Manual for vboxsf_create 🎀 this one lives in the kernel, in the vboxsf world, and it's literally the function that makes new files and folders appear inside a shared folder. no cap, it's giving "main character of the filesystem" energy. let's get into it 💖

---

🌸 SYNOPSIS 🌸

int vboxsf_create (u32 root , struct shfl_string *parsed_path , struct
shfl_createparms *create_parms );

like, that's the whole signature. three args, one int coming back at you. slay 🫶

---

🦋 ARGUMENTS 🦋

• root — the root of the shared folder where you wanna create the file. like, this is the neighborhood you're moving into 🏡
• parsed_path — the path of the file or folder, relative to the shared folder. so don't hand it an absolute path, bestie, it's already rooted for you ✨
• create_parms — the parameters for file/folder creation. this struct is carrying all the instructions, and it's also where the results come back. she's a multitasker 💅

---

👑 DESCRIPTION 👑

so what does it actually do? it creates a new file or folder, or opens one that already exists, inside a shared folder. both jobs, one function, iconic behavior honestly 💜

⚠️ big heads-up, bestie: this function always returns 0 / success unless something truly exceptional happens — out of memory, invalid arguments, etc. so a 0 return is not a promise that your file got made. keep reading, iykyk 😭

if the file or folder could not be opened or created, create_parms->handle will be set to SHFL_HANDLE_NIL on return. that's your little "nope, didn't happen" flag 🚩

in that case, the value in create_parms->result tells you why — for example SHFL_FILE_EXISTS. and here's the cute part: create_parms->result is also set on success, as additional information. so check it either way, fr fr 🌈

---

⭐ RETURN ⭐

0 or negative errno value. that's it, that's the whole vibe check 🎀
