(question) Determining delivery of data to remote end

It's not a homework. But, I didn't come out of CS, so...

Suppose I send a char to a remote machine. How do I know it received
it?
- If I write(2) to a socket and check that it returns 1 byte
written, is that sufficient to determine that the remote end
received it?
- Or, does the return value of write(2) simply means it put the char
in the outgoing buffer?

A return from write doesnt make any guarantee that remote end has
recieved it.
