|mp||The mount point to be checked.|
|nam||An mbuf containing the network address of the client.|
|exflagsp||Return parameter for the export flags for this client.|
|Return parameter for the anonymous credentials for this client.|
The VFS_CHECKEXP macro should be called on a file systems mount structure to determine if it is exported to a client whose address is contained in nam.
It is generally called before VFS_FHTOVP(9) to validate that a client has access to the file system.
The file system should call
with the address of an appropriate
.Vt netexport structure and the address of the client, nam, to verify that the client can access this file system.
The export flags and anonymous credentials specific to the client (returned by vfs_export_lookup(9)) will be returned in *exflagsp and *credanonp.
