!Description:
A routine for extracting from files in the SDP Toolkit's ephemeris or attitude file formats the names of the input files used to create them.

!Input Parameters: file_logical Identifies the file type to be read. file_version Identifies which one of those files to read.

!Output Parameters: universal_references An array for storing the universal reference strings extracted from that file.

Return Values: MODIS_E_BAD_INPUT_ARG If universal_references is null. MODIS_E_GEO If an SDP Toolkit subroutine failed. PGS_E_UNIX If a POSIX subroutine failed. PSG_S_SUCCESS Otherwise

Design Notes The ephemeris and attitude files were designed to have the same layout, at least with regard to all of the fields used by this program. The layout is defined by a C struct type. As such, it is inherently non-portable, because the C standard gives implementations a great deal of latitude for deciding how to lay out fields in a structure. However, the SDP Toolkit's own routines use this same approach, so if this rountine can't access those files correctly, neither will the Toolkit's routines. !END**************************************************************************
