Uh no.  That is the system call _wrapper_ of the library.  The system
call itself is a trap or software interrupt.

Take a look at a dictionary: <URL:http://en.wikipedia.org/wiki/System_call>

Looks more like a collection of services to me, somewhat like a
library.  A kernel that runs below a microkernel might be considered
to act partly as a program, at least if the microkernel does the
scheduling.

It's not exactly like any of this should be news to you.
