ttm_prime_handle_to_fd(9)

💅 ttm_prime_handle_to_fd — live from the Kernel API Manual 💅

Okay so bestie, welcome to the Kernel API Manual corner of the group chat 💖. This page has major main character energy for one function: ttm_prime_handle_to_fd. It is literally about returning a dma_buf fd from a ttm prime object. No cap. 🦋

🌸 NAME 🌸

ttm_prime_handle_to_fd — return a dma_buf fd from a ttm prime object. Periodt. 💅

✨ SYNOPSIS ✨

Here is the exact signature, bestie — copy it exactly, fr fr:

int ttm_prime_handle_to_fd (struct ttm_object_file *tfile , uint32_t
       handle , uint32_t flags , int *prime_fd );

🎀 ARGUMENTS 🎀

• tfile — struct ttm_object_file identifying the caller. It is giving "who dis?" energy, but for the kernel. 👑
• handle — handle to the object we are exporting from. This is the thing being sent out into the world. 🦋
• flags — flags for dma-buf creation. We just pass them on. Literally no notes, no extra seasoning. 💅
• prime_fd — the returned file descriptor. That is the fd coming back to you, bestie. 🎀
