+This function is only useful in {\it read} mode. It is the manager of the "Write-Back"
+buffer. This buffer acts like a temporary buffer where data which has to be
 read during the next read IO call are put. This is useful when you get a big
 block of data which you didn't want to read: you can replace them at the top
 of the input queue by this way.
 
+Be very careful about this call in connection with calling SeekI() on the same

+(otherwise you could SeekI() to one position, "unread" a few bytes there, SeekI()
+to another position and data would be either lost or corrupted).

 Returns the amount of bytes saved in the Write-Back buffer.
