 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 datas which has to be
+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.
