Arguments: stream &optional errorp
Returns the pathname of the file associated with stream.
cl-user(6): (setq mystream (open "myfile" :direction :output)) #<file-simple-stream #P"myfile" for output pos 0 @ #x10003650b82> cl-user(7): (stream-file-name mystream) #P"myfile" cl-user(8):
As the example shows, the returned pathname may be relative. It also may be a logical pathname. It is not necessarily the truename.
If no filename is associated with stream, the
behavior depends on the value given
for errorp: If errorp
is nil
or not given
then nil
is returned, and
if errorp is given and is
non-nil
then a type-error is signaled, based on
the stream not being a proper file-stream.
