    #define cszNxCorePriceConvert "sNxCorePriceConvert"
    typedef int (__stdcall *NxCorePriceConvert) (int lPrice, unsigned char PriceType, unsigned char PriceTypeNew);
    int PriceConvert(
        int                             lPrice,
        unsigned char                   PriceType,
        unsigned char                   PriceTypeNew
        );

Parameters

iPrice

Integer Price to be converted.

PriceType

The Price Type that iPrice is currently using.

PriceTypeNew

The Price Type to convert iPrice into.

Return Value

Returns the value of iPrice as converted into new Price Type.

Example

Here's an example of converting a price/priceType to a different priceType
