Data Fitting Function Task Status and Error Reporting

The Data Fitting routines report a task status through integer values. Negative status values indicate errors, while positive values indicate warnings. An error can be caused by invalid parameter values or a memory allocation failure.

The status codes have symbolic names predefined in the header file as macros via the #define statements.

If no error occurred, the function returns the DF_STATUS_OK code defined as zero:

: #define DF_STATUS_OK 0

In case of an error, the function returns a non-zero error code that specifies the origin of the failure. Header files define the following status codes:

Status Codes in the Data Fitting Component
Status Code	Description
Common Status Codes
DF_STATUS_OK	Operation completed successfully.
DF_ERROR_NULL_TASK	Data Fitting task is a NULL pointer.
DF_ERROR_MEM_FAILURE	Memory allocation failure.
DF_ERROR_METHOD_NOT_SUPPORTED	Requested method is not supported.
DF_ERROR_COMP_TYPE_NOT_SUPPORTED	Requested computation type is not supported.
DF_ERROR_NULL_PTR	Pointer to parameter is null.

DF_ERROR_BAD_BC	Array of boundary conditions for spline construction is not defined.
DF_ERROR_BAD_PP_COEFF	Array of piecewise polynomial spline coefficients is not defined.
DF_ERROR_BAD_PP_COEFF_HINT	Invalid flag describing the structure of the piecewise polynomial spline coefficients.
DF_ERROR_BAD_PERIODIC_VAL	Function values at the endpoints of the interpolation interval are not equal as required in periodic boundary conditions.
DF_ERROR_BAD_DATA_ATTR	Invalid attribute of the pointer to be set or modified in Data Fitting task descriptor with the df?EditIdxPtr task editor.
DF_ERROR_BAD_DATA_IDX	Index of the pointer to be set or modified in the Data Fitting task descriptor with the df?EditIdxPtr task editor is out of the pre-defined range.
Data Fitting Computation Operations
DF_ERROR_BAD_NSITE	Invalid number of interpolation sites.
DF_ERROR_BAD_SITE	Array of interpolation sites is not defined.
DF_ERROR_BAD_SITE_HINT	Invalid flag describing the structure of interpolation sites.
DF_ERROR_BAD_NDORDER	Invalid size of the array defining derivative orders to be computed at interpolation sites.
DF_ERROR_BAD_DORDER	Array defining derivative orders to be computed at interpolation sites is not defined.
DF_ERROR_BAD_DATA_HINT	Invalid flag providing additional information about partition or interpolation sites.
DF_ERROR_BAD_INTERP	Array of spline-based interpolation results is not defined.
DF_ERROR_BAD_INTERP_HINT	Invalid flag defining the structure of spline-based interpolation results.
DF_ERROR_BAD_CELL_IDX	Array of indices of partition cells containing interpolation sites is not defined.
DF_ERROR_BAD_NLIM	Invalid size of arrays containing integration limits.
DF_ERROR_BAD_LLIM	Array of the left-side integration limits is not defined.
DF_ERROR_BAD_RLIM	Array of the right-side integration limits is not defined.
DF_ERROR_BAD_INTEGR	Array of spline-based integration results is not defined.
DF_ERROR_BAD_INTEGR_HINT	Invalid flag providing the structure of the array of spline-based integration results.
DF_ERROR_BAD_LOOKUP_INTERP_SITE	Bad site provided for interpolation with look-up interpolator.

NOTE:

The routine that estimates piecewise polynomial cubic spline coefficients can return internal error codes related to the specifics of the implementation. Such error codes indicate invalid input data or other issues unrelated to Data Fitting routines.
