NullBitVector
a NullBitVector array previously allocated by the caller.
The data type used to access the NullBitVector is defined in sqltypes_td.h as:
typedef unsigned char NullBitVecType;
indexValue
the bit in the NullBitVector to be checked, as specified in row-major order for an ARRAY. Valid values start from 0.
bufSize
the size in bytes of the NullBitVector as allocated by the caller prior to initialization of the NullBitVector by setting all bytes to 0.
