of events in this block (not counting dictionary).

headerLength

uint32_t evioBlockHeaderV4_t::headerLength

length of this block header in 32-bit words (always 8).

length

uint32_t evioBlockHeaderV4_t::length

total length of block in 32-bit words including this complete header.

magicNumber

uint32_t evioBlockHeaderV4_t::magicNumber
