class output_descr :?blocking:bool -> ?start_pos_out:int -> Unix.file_descr ->
raw_out_channel
raw_out_channel
for the passed file descriptor, which must
be open for writing.
The pos_out
method returns logical positions, i.e. it counts the number
of written octets. It is not tried to determine the real file position.
The method close_out
also closes the file descriptor.
This class also supports Win32 proxy descriptors referring to an output channel.
blocking
: Whether the channel waits until it can output if it is not
possible to write to the (non-blocking) descriptor. Defaults to true
.start_pos_out
: The position to which pos_out
is initialized when
the channel is created, by default 0
