WriteAt

Declaration

virtual bool WriteAt(uint64_t Offset, const uint8_t* Data, size_t Size) = 0;

Header: #include "Native/Net/NetJoin.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrainCore"); in your module’s Build.cs.
Stability: Experimental: supported, may change in a minor version, with a changelog line.
Thread: Made and written on the drain's thread, one call at a time; ReadAt on any thread, also while a WriteAt runs, and only of bytes a WriteAt wrote. (the rule of IJoinReceiveStore)

Name	Type	Default	Meaning
`Offset`	`uint64_t`	—	—
`Data`	`const uint8_t*`	—	—
`Size`	`size_t`	—	—

false when the bytes could not be written: the reader stops (EJoinStreamError::StoreFailed) and keeps what it holds in memory.
