This interface can be used to read/write certain properties of the active DSS object. The structure of the interface is as follows:


void  SettingsV(int32_t Parameter, uintptr_t *Pointer, int32_t *Type, int32_t *Size);


In this version of the DLL the API requires 4 arguments Some of these arguments are informative while others provide data access through memory address. This avoids creating unnecessary copies of the same data across the system. The 4 arguments used in this API are:


  • Parameter: Indicates the data array that wants to be accessed/written.
  • Pointer: Is the pointer to the array structure.
  • Type: Is the type of data contained in the structure, it can be one of: 0 - Boolean, 1- Integer (32 bit), 2- double (64 bit), 3- Complex, 4- String.
  • Size: Is the size in Bytes of the structure, it only considers the elements inside the structure without the identifiers added by DSS. In the case of array of strings includes the null byte (0) between the elements of the array.  


The return values depend on the given Parameter, which can be one of the following:


Parameter 0: Settings.UERegs read

This parameter returns a pointer to an array of integers containing the Energy Meter registers to use for computing UE.


Parameter 1: Settings.UERegs write

This parameter allows to write the array of Integers defining Energy Meter registers to use for computing UE using the given pointer. The argument Pointer must be provided by the caller pointing to an array of integers containing the new data. The argument mySize must also contain the length of the array of integers.


Parameter 2: Settings.LossRegs read

This parameter returns a pointer to an array of integers containing the Energy Meter registers to use for computing Losses.


Parameter 3: Settings.LossRegs write

This parameter allows to write the array of Integers defining Energy Meter registers to use for computing Losses using the given pointer. The argument Pointer must be provided by the caller pointing to an array of integers containing the new data. The argument mySize must also contain the length of the array of integers.


Parameter 4: Settings.VoltageBases read

This parameter returns a pointer to an array of doubles containing defining the legal voltage bases in kV L-L.


Parameter 5: Settings.VoltageBases write

This parameter allows to write the array of doubles defining the legal voltage bases in kV (L-L) using the given pointer. The argument Pointer must be provided by the caller pointing to an array of double containing the new data. The argument mySize must also contain the length of the array of doubles.
