You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: checkseccomp.go
    path of file: ./repos/podman/test/checkseccomp
    
    the code of the file until where you have to start completion: //go:build seccomp

package main

import (
	"os"

	"golang.org/x/sys/unix"
)

func main() {
	// Check if Seccomp is supported, via CONFIG_SECCOMP.
    
func main() {
	// Check if Seccomp is supported, via CONFIG_SECCOMP.
	if err := unix.Prctl(unix.PR_GET_SECCOMP, 0, 0, 0, 0); err != unix.EINVAL {
		// Make sure the kernel has CONFIG_SECCOMP_FILTER.
		if err := unix.Prctl(unix.PR_SET_SECCOMP, unix.SECCOMP_MODE_FILTER, 0, 0, 0); err != unix.EINVAL {
			os.Exit(0)
		}
	}
	os.Exit(1)
}
