Hi Ricardo,
APR is like a wrapper around existing OS specific implementations of APIs.
Some of the APIs operate at kernel level. I am not sure whether i understood
the question. But if u are talking about using kernel concepts of
Semaphores, shared memory and all, yes APR operates at that level.

APR uses the C library, and other libraries. It's still off-topic for
this list.

APR is written in C and makes system calls to the kernel. Nothing in APR
is kernel level, and nothing in it runs with kernel privileges, it is
all userland code.

Hi,
APR make the same things that libraries C ??
Because C make system calls to kernel level.
I would want know if APR do system calls like C!!! APR works like C ??
Thank you !!

You'll have to do some research about including C libraries in kernel modules.

This is the Apache HTTP Server users list.
I was under the impression that you couldn't even use libc in the
kernel, much less any of the libraries APR links to or APR itself.
