val add_channel : Core_kernel.Bigbuffer.t -> Core.In_channel.t -> int -> unitadd_channel b ic n reads exactly n characters from the input channel ic and stores them at the end of buffer b. Raises End_of_file if the channel contains fewer than n characters.
val output_buffer : Core.Out_channel.t -> Core_kernel.Bigbuffer.t -> unitoutput_buffer oc b writes the current contents of buffer b on the output channel oc.
val md5 : Core_kernel.Bigbuffer.t -> Core.Md5.tDigest the current contents of the buffer.
