It seems to be nonsense. But this is nonsense, ideal for buffers. If the buffer is implemented as an array, then fill pointer just marks the boundary of the filled part of the buffer, and adding a buffer (moving away from the fill pointer-a) is carried out using the vector-push. Or a buffer can be filled with the format-a. If you work with the same buffer C, fill pointer simulates a pointer to the last completed item."
Filling a buffer is usually done this way: http://dlang.org/phobos/std_stdio.html#.File.rawRead
