+ <p><c>allocate/3</c> can be used to preallocate space for a file.</p>
+ <p>This function only succeeds in platforms that implement this
+ feature. When it succeeds, space is preallocated for the file but
+ the file size might not be updated. This behaviour depends on the
+ preallocation implementation. To guarantee the file size is updated
+ one must truncate the file to the new size.</p>
