Function Documentation

int hdf_add_empty_sds (  const char *  file, const char *  sds_name, int32  sds_type, int32  rank, int32 *  dimensions, const float64  cal = 1., const float64  offset = 0., const float64  cal_err = 0., const float64  off_err = 0. )

creates a new dataset in an existing hdf file (will fail if a dataset with the same name already exists) Parameters: file  the hdf file to update sds_name  the name of the new dataset (sds: scientific dataset) to add sds_type  the hdf type code of the new dataset, e.g. DFNT_UINT16, DFNT_FLOAT32... (see HDF documentation for valid type codes) rank  the rank (number of dimensions) of the new dataset to create dimensions  a pointer to the array of dimensions of the new dataset cal  the calibration factor linked to the new dataset (also named slope); relation between calibrated and uncalibrated data is: cal_data = cal*(uncal_data - offset) offset  the offset factor linked to the new dataset; relation between calibrated and uncalibrated data is: cal_data = cal*(uncal_data - offset) cal_err  error on the calibration factor (unused for the time being) off_err  error on the offset (unused for the time being) Returns: 0 on success, -1 on failure

int hdf_create_empty_file (  const char *  file  )

creates a new (empty) hdf file Parameters: file  the name of the file to create Returns: 0 on success, -1 on failure
