class type compl_out_channel =Further methods usually supported by ocamlnet channel implementations. These methods are only reasonable when the channel is of blocking type, i.e. waits for output readiness when the underlying resource currently cannot process enough data. Implementations may choose to fail when they detect the channel is non-blocking.
intargument specifies. The octets are taken from the string position denoted by the first
method output_channel :
?len:int -> in_obj_channel -> unit
in_obj_channeluntil the end of the input channel is reached.
len: If passed, at most this number of octets are read from the input channel and written to this channel.
