ROOT::Internal::RRawFile::RIOVecLimits Struct Reference

Implementations may enforce limits on the use of vector reads.

These limits can depend on the server or the specific file opened and can be queried per RRawFile object through GetReadVLimits(). Note that due to such limits, a vector read with a single request can behave differently from a Read() call.
