Is WriteFile atomic?

由 我与影子孤独终老i 提交于 2021-02-07 03:07:29
问题 I'm designing a system that will write time series data to a file. The data is blocks of 8 bytes divided into two 4 bytes parts, time and payload.

Since the file will only contain these blocks (there is no "structure" of the file so it's not possible to reconstruct a damaged file), added one after each other, it's vital that
