DC_DESCRIPTOR_GET_TRANSPORTS(3)

💅 DC_DESCRIPTOR_GET_TRANSPORTS(3)

okay so bestie, this one lives in the Library Functions Manual section — the manual name is literally DC_DESCRIPTOR_GET_TRANSP(3) and no, that's not a typo, the header just cut it off. iconic of it honestly. anyway. let's get into it ✨

---

🌸 NAME 🌸

dc_descriptor_get_transports — gets the transports supported by the given descriptor. that's the whole vibe. it's a getter. it gets. 💅

---

🎀 LIBRARY 🎀

library “libdivecomputer” 🫶

---

✨ SYNOPSIS ✨

#include <libdivecomputer/descriptor.h>

unsigned int
dc_descriptor_get_transports(const dc_descriptor_t *descriptor);

---

🦋 DESCRIPTION 🦋

okay so what this does is it gets the transports supported by the given descriptor. no cap, that's it. 🫶

and like, where do you even find a descriptor? lowkey the descriptor is usually found by searching through dc_descriptor_iterator_new(3). so go do that first, bestie. iykyk 💜

---

🌈 RETURN VALUES 🌈

it returns a union (that's a bitwise OR, for the record 🧚) of the transports supported by the given descriptor. so like, all the vibes mashed together into one unsigned int.

the result is a combination of:

• DC_TRANSPORT_USB
• DC_TRANSPORT_USBHID
• DC_TRANSPORT_BLE
• DC_TRANSPORT_BLUETOOTH
• DC_TRANSPORT_SERIAL
• DC_TRANSPORT_IRDA

and to determine if a specific transport is supported, use the following code, periodt:

unsigned int transports = dc_descriptor_get_transports(descriptor);
if(transports & DC_TRANSPORT_USBHID) {
    // Device supports USB HID as transport
}

like, it's giving bitmask. it's giving &. she ate 🔥
