On Windows I/O completion ports, say I do this:
void function()
{
WSASend("1111"); // A
WSASend("2222"); // B
WSASend("3333"); // C
}
If I got a "write-complete" that says 3 bytes of WSASend() A were sent, is it possible that right after that I'll get a "write-complete" that tells me that some or all of B & C were sent, or will TCP will hold them until I re-issue a WSASend() call with the rest of A's data? Or will TCP complete it automatically?
