I wasn't referring to a program you can access from the shell, but to a
system call, a much lower-level thing.  Applications invoke system calls,
at the C/assembly level, to request services from the kernel; /bin/mv uses
the rename system call (as well as a fair number of others, I'm sure).
Check section 2 of your unix manual for more details: either "man 2 rename"
or "man -s 2 rename", depending on your particular flavor of Unix.
