System call code - nice()

Hi there, i'm trying to find the implementation code for the system call nice().
Since it's a system call i'm having problems finding where it would be? is it in the linux kernel directory somewhere?

I would assume it would be a file called nice.c or something like this.

Thanks in advance!

NAME
nice -- execute a utility with an altered scheduling priority SYNOPSIS
nice [-n increment] utility [argument ...] DESCRIPTION
nice runs utility at an altered scheduling priority. If an increment is given, it is used; otherwise an increment of 10 is assumed. The super-user can run utilities with priorities higher than normal by using a negative increment. The priority can be adjusted over a range of -20 (the highest) to 20 (the lowest). Available options: -n increment A positive or negative decimal integer used to modify the system scheduling priority of utility. DIAGNOSTICS
The nice utility shall exit with one of the following values: 1-125 An error occurred in the nice utility. 126 The utility was found but could not be invoked. 127 The utility could not be found. Otherwise, the exit status of nice shall be that of utility. COMPATIBILITY
The historic -increment option has been deprecated but is still supported in this implementation. SEE ALSO
csh(1), getpriority(2), setpriority(2), renice(8) STANDARDS
The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). HISTORY
A nice utility appeared in Version 6 AT&T UNIX. BUGS
nice is built into csh(1) with a slightly different syntax than described here. The form 'nice +10' nices to positive nice, and 'nice -10' can be used by the super-user to give a process more of the processor. BSD
