The following code obtains a vnode token for the file or directory specified via the input FID, residing within the mounted file system represented by the input VFS token. Previously, the FID might have been obtained from an attribute structure returned by v_lookup, and the VFS token via v_rpn. For the callable service, see v_get (BPX1VGT, BPX4VGT) — Convert an FID to a vnode Token. For the data structure, see BPXYOSS — Map operating system specific information.
