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 integer constants via the PARAMETER operators.
If no error occurred, the function returns the DF_STATUS_OK code defined as zero:
- INTEGER, PARAMETER::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:
