FNC_CheckNullBitVectorByElemIndex takes NullBitVector, indexValue, bufSize, arrayScope, and numDimensions as input and returns the value of the specified presence bit in the NullBitVector.

After calling an FNC routine such as FNC_GetArrayElements, which sets presence information in a NullBitVector, you can call FNC_CheckNullBitVectorByElemIndex to interpret the results of the NullBitVector returned by FNC_GetArrayElements.

For more information about using NullBitVectors, see Checking and Setting the NullBitVector.
