Does alsa-lib call this kernel api? #204

Closed Nick0412 closed 2 years ago

Nick0412 commented 2 years ago

Where in the alsa library does it reference the alsa kernel api: https://www.kernel.org/doc/html/latest/sound/kernel-api/alsa-driver-api.html?

Do these two apis interact at all?

Nick0412 commented 2 years ago

I should add, where are the system calls made in alsa-lib that call the kernel alsa api?

The user space <-> kernel communication is using the character devices (open/close/ioctl/read/write).

EDIT: You refer the internal kernel API for drivers. It's not visible for applications at all.
