systemcall

I am working on x86_64 machine. My linux kernel is also 64 bit kernel. As there are different ways to implement a system call (int 80, syscall, sysenter), i wanted to know what type of system call my machine is using. I am newbie to linux. I have written a demo program.

include

int main() { getpid(); return 0; }

getpid() does one system call. Can anybody give me a method to find which type of system call will be used by my machine for this program.. Thank you....
