trfh = trfclose(trfhin);
Usage: trfh = trfopen(trfhin);
Description: Close the trf file pointed to by the trf_handle trfhin and return a
trf_handle which points has an invalid file identifier.
trfhin: A trf_handle structure which has been created using trf_open.
trfh: A trf_handle structure which contains an invalid file pointer.
So that user's can keep track of whether or not a trf file is opened or
closed, it is generally a good idea to use only one trf_handle for loading
data from a particular file. In this way, users will not inadvertantly
attempt to load data from a closed or otherwise invalid file. For this
reason, this routine ought to be used in a form where trfhin and trfh
have the same name. That is, t=trfclose(t) should be the typical form.
