| 1610 | * then it's possible to simply swap the caller's buffer with the |
| 1611 | * mux's output buffer and adjust offsets and length to match the |
| 1612 | * entire DATA HTX block in the middle. In this case we perform a |
| 1613 | * true zero-copy operation from end-to-end. This is the situation |
| 1614 | * that happens all the time with large files. Second, if this is not |
| 1615 | * possible, but the mux's output buffer is empty, we still have an |
| 1616 | * opportunity to avoid the copy to the intermediary buffer, by making |
| 1617 | * the intermediary buffer's area point to the output buffer's area. |
| 1618 | * In this case we want to skip the HTX header to make sure that copies |
| 1619 | * remain aligned and that this operation remains possible all the |
| 1620 | * time. This goes for headers, data blocks and any data extracted from |
| 1621 | * the HTX blocks. |
