what is the library function for shutting down linux?

I am writing a program in linux that shuts down the system as if executing "shutdown -h now" under the shell. I wonder which library function (in C) I shall use for that. Thanks.

try
system("shutdown -h now");

I have never tried it myself though.

To see which libraries is being used:

Code:

ldd /sbin/shutdown
