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.
