As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard) with prefixed line numbers and code folding option. Alternatively you can here view or download the uninterpreted source code file. For more information about "sbuf_stream.h" see the Fossies "Dox" file reference documentation and the last Fossies "Diffs" side-by-side code changes report: 1.4.5_vs_1.5.0.
