# Module Iobuf.Poke

    module Poke: sig .. end

`Poke.bin_prot X.bin_write_t t x` writes `x` to the beginning of `t` in binary form without advancing. You can use `X.bin_size_t` to tell how long it was. `X.bin_write_t` is only allowed to write that portion of the buffer to which you have access.

    val decimal : (Core_kernel.Std.read_write, 'w) Iobuf.t -> pos:int -> int -> int

`decimal t ~pos i` returns the number of bytes written at `pos`.
