/***
* === Internal structure [[internal]]
*
* You aren't allowed to do anything with the underlying buffers while these
* are connected into fbmulti.
*
- * You may init a fbmulti by @fbmulti_create(bufsize, fb1, fb2, ..., NULL).
- * This call returns a fastbuf that concatenates all the given fastbufs.
- * The last parameter of @fbmulti_create must be NULL.
+ * The fbmulti is inited by @fbmulti_create(). It returns an empty fbmulti.
+ * Then you call @fbmulti_append() for each fbmulti.
*
* If @bclose() is called on fbmulti, all the underlying buffers get closed
* recursively.
*
- * You may init a fbmulti by @fbmulti_create(bufsize) with no underlying buffers
- * and then append the underlying buffers one by one.
- *
- * If used in some formatter, you'll probably have a large and deep structure
- * of nested fastbufs. Just before reading from the fbmulti, you may call
- * @fbmulti_flatten() to flatten the structure. After @fbmulti_flatten(), the
- * fbmulti is seeked to the beginning, flushed and ready to read the whole buffer.
- *
- * If you want to remove a fastbuf from the chain, just call @fbmulti_remove
- * where the second parameter is a pointer to the removed fastbuf. If you pass
- * NULL, all the underlying fastbufs are removed.
+ * If you want to keep an underlying fastbuf open after @bclose, just remove it
+ * by @fbmulti_remove where the second parameter is a pointer to the removed
+ * fastbuf. If you pass NULL, all the underlying fastbufs are removed.
*
- * When a fastbuf is removed from the chain, the overall position may change:
- * If bstop pointed into it, after removal it points to the boundary of the
- * previous and next fastbufs. Length of the removed fastbuf is subtracted from
- * the overall offset of all the fastbufs after the removed fb in the chain.
+ * After @fbmulti_remove, the state of the fbmulti is undefined. The only allowed
+ * operation is either another @fbmulti_remove or @bclose on the fbmulti.
