| 1772 | * First, if the mux's buffer is empty and the htx area contains |
| 1773 | * exactly one data block of the same size as the requested count, |
| 1774 | * then it's possible to simply swap the caller's buffer with the |
| 1775 | * mux's output buffer and adjust offsets and length to match the |
| 1776 | * entire DATA HTX block in the middle. In this case we perform a |
| 1777 | * true zero-copy operation from end-to-end. This is the situation |
| 1778 | * that happens all the time with large files. Second, if this is not |
| 1779 | * possible, but the mux's output buffer is empty, we still have an |
| 1780 | * opportunity to avoid the copy to the intermediary buffer, by making |
| 1781 | * the intermediary buffer's area point to the output buffer's area. |
| 1782 | * In this case we want to skip the HTX header to make sure that copies |
| 1783 | * remain aligned and that this operation remains possible all the |
| 1784 | * time. This goes for headers, data blocks and any data extracted from |
| 1785 | * the HTX blocks. |
