Is the "posix kernel API" the same as the "linux system calls"?
I'm trying to understand some general things about the linux kernel
compared to the posix kernel API and system calls.
So here are my questions:
Is the "posix kernel API" the same as the linux "system calls"? If not,
what is the difference?
From what I understand, system calls are the only interface that user
programs can use to interact with the kernel.
Are system calls a form of kernel function? Can/do kernel functions
call system calls?
