NAME

NS_GET_NSTYPE - discovering the namespace type

bash

#include <linux/nsfs.h>\n  /* Definition of \nNS_GET_NSTYPE\n */
\n#include <sys/ioctl.h>

bash

int ioctl(int \nfd\n, 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.
