Hello everybody.
What is the Long64_t data type? I had search about it but I didn't find it.
I wanna to know its length and when it can be use?

It's not a standard type. But, probably it just means a signed 64-bit integer.
std::int64_t is available in <cstdint>.

Doesn't really help explain much, other than it is a very specific non-standard data type.

You say you did a search and couldn't find anything. I did a search (two actually) and was able to find a number of links:
