"Use the force, read the source"

uclibc:
http://git.uclibc.org/uClibc/tree/libc/string/generic/memcpy.c

glibc:
http://sourceware.org/git/?p=glibc.git;a=blob;f=string/memcpy.c;h=e167e85d7b31bda4e85ec7836631da2a15acf860;hb=c0da14cdda1fa552262ce3624156194eef43e973

Which means: No, memcpy (meaning the userspace function that gets
included by "string.h") is *not* a system call.

Hope this helps,
Ezequiel.
