NS_GET_NSTYPE - discovering the namespace type
#include <linux/nsfs.h> /* Definition of NS_GET_NSTYPE */
#include <sys/ioctl.h>
int ioctl(int fd, NS_GET_NSTYPE);
The NS_GET_NSTYPE operation can be used to discover the type of
namespace referred to by the file descriptor fd.
fd refers to a /proc/pid/ns/* file.
On success, the return value is one of the CLONE_NEW* values that
can be specified to clone(2) or unshare(2) in order to create a
namespace.
On error, -1 is returned, and errno is set to indicate the error.
