startUint32Index: the zero-based index from which on data should be packed. Can be omitted in which case 0 is used
uint32Count: the amount of uint32s that should be packed. Can be omitted in which case 0 is used (which indicates that the maximum available uint32s should be packed from the indicated startUint32Index) |
