💅 internals(3) — the libmtp lore drop

okay bestie, pull up a chair 🎀 this is the internals page from the Library Functions Manual — it's the little backstage tour of libmtp, and honestly? it ate. let's get into it. ✨

---

🌸 NAME

libmtp — internals 🫶

the vibes: this is the inside scoop page. not the glamorous front-facing API, the guts. 💜

---

✨ SYNOPSIS

🧚 Functions

void LIBMTP_Set_Debug (int)
void LIBMTP_Init (void)
int LIBMTP_Get_Supported_Devices_List (LIBMTP_device_entry_t **const,
    int *const)

three functions. that's the whole roster. iconic trio energy fr fr. 👑

🔥 Detailed Description

(no further words on this one — the details live down in the function docs below, bestie, no cap)

---

💖 Function Documentation

🌈 int LIBMTP_Get_Supported_Devices_List (LIBMTP_device_entry_t **const devices, int *const numdevs)

literally the "who's invited to the party" function — get a list of the supported USB devices. 💃

okay so here's the thing, and the devs are begging you here: they depend on users of this library to constantly add to the list of supported devices. that's a group project and everyone has to do their part, no freeloaders 😭

what they need from you is:

• the device name 🏷️
• the USB Vendor ID (VID)
• the USB Product ID (PID)

put all that into a bug ticket at the project homepage, please and thank you. 🙏

and why do they need the VID/PID, you ask? because the VID/PID is what lets e.g. udev lift the device to console userspace access when it's plugged in. so like, your ticket is literally what makes the device get access. main character contribution honestly. ⭐

Parameters

• devices — a pointer to a pointer that will hold a device list after the call to this function, if it was successful.
• numdevs — a pointer to an integer that will hold the number of devices in the device list if the call was successful.

Returns

0 if the list was successful retrieved, any other value means failure. 💀

note: yes, the original really does say "successful retrieved" — i'm not fixing it, that's her wording and we respect it. 💅

🦋 void LIBMTP_Init (void )

Initialize the library. 🎬

you are only supposed to call this one, before using the library for the first time in a program.

⚠️ Never re-initialize libmtp! like, ever. do not do it. this is the "don't touch the thermostat" of libmtp. 🚫

the only thing this does at the moment is to initialise the filetype mapping table, as well as load MTPZ data if necessary. lowkey a lot for one little call, highkey slay. 💖

🍓 void LIBMTP_Set_Debug (int level)

Set the debug level. 🔧

by default, the debug level is set to '0' (disable).

so yeah, if you want the tea, you gotta ask for the tea. ☕

okay that's the whole page bestie, you're officially educated. go forth and add your device to that list, the devs are counting on you 🫶

<anything>this lil' internals page came to you from libmtp, Version 1.1.23, and it's chilling in section internals(3) of the manual. periodt. 💅🎀✨</anything>
