Access to Tabular Data

• SDDS_GetColumn -- Returns a pointer to an array of data values from a single column of the tabular portion of the current data table. Only rows that are ``of interest'' are returned.
• SDDS_GetColumnInDoubles -- Returns a pointer to an array of doubles containing the numeric data values (converted to double if necessary) from a single column of the tabular portion of the current data table. Only rows that are ``of interest'' are returned.
• SDDS_GetMatrixFromColumn -- Returns a pointer to a two-dimensional array of data values from a single column of the tabular portion of the current data table. Only rows that are ``of interest'' are included. The dimensions of the array are supplied by the caller (from parameters stored in the data set, for example).
• SDDS_GetMatrixOfRows -- Returns a pointer to a two-dimensional array of data values from the rows and columns ``of interest''. The columns are ordered as defined by calls to SDDS_SetColumnsOfInterest, and must have the same data type.
• SDDS_GetRow -- Returns a pointer to a single row containing data values from the columns ``of interest''. Only the rows ``of interest'' are returned. The columns are ordered as defined by calls to SDDS_SetColumnsOfInterest, and must have the same data type.
• SDDS_GetValue -- Returns a pointer to a single value from the tabular data. The data is requested by giving the column name and the row number. Only values from the rows ``of interest'' are returned.
