Function: tramp-make-tramp-file-name
tramp-make-tramp-file-name is a byte-compiled function defined in
tramp.el.gz.
Signature
(tramp-make-tramp-file-name VEC &optional LOCALNAME HOP)
Documentation
Construct a Tramp file name from ARGS.
ARGS could have two different signatures. The first one is of type (VEC &optional LOCALNAME HOP). If LOCALNAME is nil, the value in VEC is used. If it is a symbol, a null localname will be used. Otherwise, LOCALNAME is expected to be a string, which will be used. If HOP is nil, the value in VEC is used. If it is a symbol, a null hop will be used. Otherwise, HOP is expected to be a string, which will be used.
The other signature exists for backward compatibility. It has the form (METHOD USER DOMAIN HOST PORT LOCALNAME &optional HOP).
