NAME

       nvme_get_nsid - Retrieve the NSID from a namespace file descriptor

SYNOPSIS

       int nvme_get_nsid (int fd , __u32 *nsid );

ARGUMENTS

       fd          File descriptor of nvme namespace

       nsid        User pointer to namespace id

DESCRIPTION

       This  should  only  be  sent to namespace handles, not to controllers. The kernel's interface returns the
       nsid as the return value. This is unfortunate for many  architectures  that  are  incapable  of  allowing
       distinguishing a namespace id > 0x80000000 from a negative error number.

RETURN

       0 if nsid was set successfully or -1 with errno set otherwise.
