comment What is meant by “a system call” if not the implementation in the programing language?
Do you have an example of the "wrapper function" and a actual system call? (file paths in Linux or links to sources)

@Gilles I cant access it, the flash is a storage for an embedded device. The only approach is through ssh or serial cable.

I'm interested in the Alsa driver stack, so once i figured it isn't just a get a single vendor supplied file to compile with your kernel kind of problem problem (cause i manged to do that). I wanted to check if I have the correct conceptual overview.
