I know you can read the file a CHUNK at a time and send it over the
network, but what I want to know is if you can just stream the whole
file.

Like

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
fs:TfileStream;fs :=
TFileStream.Create('Myfile.txt',fmOpenRead);fs.sendstreamt(aSocket); 
something like that.

That is entirely dependent on the capabilities of the socket library
you are using.  If it has an API for sending an entire file/TStream
for you, then feel free to use it (it will likely just chunk the data
automatically for you).  Otherwise, you have to chunk the data
manually, like you are already doing.

on linux you can use senfile() syscall.... on windows you use. buffers
or  transmitfile() of winsocks2 or you can implement memory maped io
and send the hole memory of the file to the socket... your choice
