- * Extent files.
- *
- * This modules provides a familiar interface for handling files through an
- * indirection layer of extents, which are contiguous chunks of variable length
- * at arbitrary offsets within a file.  Once an extent file handle is obtained,
- * users may read, write and seek as they do with ordinary files, having the I/O
- * with the underlying file done for them by the extent file implementation. The
- * implementation supports "sparse extents", which are assumed to contain zeros
- * but otherwise have no actual representation in the underlying file; these are
- * denoted by negative offset values.
- *
- * Unlike ordinary files, the size of an extent file is fixed; it is not
- * truncated on open, nor is writing past the extent span allowed. Also, writing
- * to a sparse extent has no effect and will not raise an error.

- * (read-only), "w" (write-only) or "r+"/"w+" (read-write); the underlying file
- * is neither created (if not present) nor truncated (if present) when opened
- * for writing. The function |ex_free|, if not NULL, will be called to
- * deallocate the extent array once the file object is closed.  Returns a FILE
- * pointer that can be used with ordinary stream functions (e.g.  fread), or
