Function Documentation

int nfs_mount

(

struct nfs_mount_request *

info

)

nfs_mount - Obtain an NFS file handle for the given host and path : pointer to mount request arguments

Uses default timeout parameters specified by underlying transport.

Definition at line 144 of file mount_clnt.c.

void nfs_umount

(

const struct nfs_mount_request *

info

)

nfs_umount - Notify a server that we have unmounted this export : pointer to umount request arguments

MOUNTPROC_UMNT is advisory, so we set a short timeout, and always use UDP.
