cti_get_port_type_fpga(9)

💅 cti_get_port_type_fpga — get the port type of a CTI FPGA card ✨

okay so bestie, welcome to the Kernel API Manual 🎀 we're literally about to find out what kind of port a CTI FPGA card is serving, and honestly? it's giving "one tiny helper function with main character energy" 👑

---

🌸 SYNOPSIS 🌸

enum cti_port_type cti_get_port_type_fpga (struct exar8250 *priv ,
struct pci_dev *pcidev , unsigned int port_num );

like, three args, one return, no drama 💅

---

🦋 ARGUMENTS 🦋

• priv — the device's private structure, aka its little inner world 🙈
• pcidev — pointer to the PCI device for this port, the actual hardware bestie 🔥
• port_num — which port you wanna get the type of, pick a number, any number ✨

---

⭐ DESCRIPTION ⭐

so here's the tea ☕ — FPGA based cards port types are based on PCI IDs. that's it, that's the whole vibe. no cap 🧚

---

💖 RETURN 💖

• port type on success 🎉
• CTI_PORT_TYPE_NONE on failure 😭

like go read those too, they're iconic, iykyk 👑

lowkey reminder: failure gives you CTI_PORT_TYPE_NONE, so bestie please actually check your return value before you do anything unhinged with it 💀
