media_devnode_create(9)

💖 media_devnode_create(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual. this page is literally about media_devnode_create, the function that creates and initializes a device node interface. no cap. 🎀

✨ NAME ✨

media_devnode_create — creates and initializes a device node interface 💅

🦋 SYNOPSIS 🦋

struct media_intf_devnode * media_devnode_create (struct media_device
       *mdev , u32 type , u32 flags , u32 major , u32 minor );

🌸 ARGUMENTS 🌸

okay this function takes five things, and yes every single one matters:

• mdev — pointer to struct media_device.
• type — type of the interface, as given by :ref:`include/uapi/linux/media.h <media_header>` (seek for MEDIA_INTF_T_*) macros.
• flags — Interface flags, as defined in :ref:`include/uapi/linux/media.h <media_header>` (seek for MEDIA_INTF_FL_*)
• major — Device node major number.
• minor — Device node minor number.

💫 RETURN 💫

if succeeded, returns a pointer to the newly allocated media_intf_devnode pointer. that's the win condition, bestie. ✨

💜 DESCRIPTION 💜

NOTE: Currently, no flags for media_interface is defined.

that's it, that's the note. 🫶
