class type raw_out_channel =object..end
Basic Unix-level class type for output channels as used by ocamlnet. In addition to the recommended standard, ocamlnet always support a position counter
method pos_out : intReturns the current channel position. This position can be expected
to be consistent with the returned number of bytes of output, i.e.
when output returns n, the position is advanced by n.
As seek operations are outside the scope of Netchannels,
implementations may or may not take seek operations into account.
