#define NFSCTL_GETFH        6    /* get an fh (used by mountd) */

struct nfsctl_arg { int ca_version; /* safeguard */ union { struct nfsctl_svc u_svc; struct nfsctl_client u_client; struct nfsctl_export u_export; struct nfsctl_uidmap u_umap; struct nfsctl_fhparm u_getfh; unsigned int u_debug; } u; }

union nfsctl_res { struct knfs_fh cr_getfh; unsigned int cr_debug; };
