description: Initializes a SDDS_TABLE structure for use in reading data from a SDDS file. This involves
opening the file but not reading a header. It is assumed that the file contains no header, and
that the caller will set up the SDDS_TABLE structure using calls to the SDDS_Define X
routines. This is way of using SDDS is not recommended, as it defeats the purpose of having
a self-describing file by imbedding the description in a program.
