Checks the value of one bit in a NullBitVector that was previously allocated by the caller. The bit to be checked may be referenced by the ARRAY type element index as specified by dimension.
FNC_CheckNullBitVectorByElemIndex returns an integer which is the value of the specified bit that was checked in the NullBitVector. Valid values returned are:
- 1, meaning that the corresponding element in the ARRAY contains a non-null value.
- 0, meaning that the corresponding element in the ARRAY is present but set to NULL.
