htx_xfer() function should replace htx_xfer_blks(). It will be a bit easier to maintain and to use. The behavior of htx_xfer() can be changed by calling it with specific flags: * HTX_XFER_KEEP_SRC_BLKS: Blocks from the source message are just copied * HTX_XFER_PARTIAL_HDRS_COPY: It is allowed to partially xfer headers or trailers * HTX_XFER_HDRS_ONLY: only headers are xferred By default (HTX_XFER_DEFAULT or 0), all blocks from the source message are moved into to the destination mesage. So copied in the destination messageand removed from the source message. The caller must still define the maximum amount of data (including meta-data) that can be xferred. It is no longer necessary to specify a block type to stop the copy. Most of time, with htx_xfer_blks(), this parameter was set to HTX_BLK_UNUSED. And otherwise it was only specified to transfer headers. It is important to not that the caller is responsible to verify the original HTX message is well-formated. Especially, it must be sure headers part and trailers part are complete (finished by EOH/EOT block). For now, htx_xfer_blks() is not removed for compatiblity reason. But it is deprecated. |
