--- Comment #3 from Tom Hughes <t...@compton.nu> ---
This seems to do the job:
#define _GNU_SOURCE
#include <sched.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/syscall.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <unistd.h>
int main(int argc, char **argv)
{
int pid;
int fd;
if ((pid = syscall(SYS_clone, CLONE_VFORK | CLONE_PIDFD, NULL, &fd, NULL, 0))
< 0)
{
perror("clone");
}
else if (pid > 0)
{
printf("pidfd = %d\n", fd);
waitpid(pid, NULL, 0);
}
exit(0);
}
