Normally I use yy030 but I have been experimenting with this instead. Seems to be slightly faster and smaller than similar programs from html-xml-utils. https://www.w3.org/Tools/HTML-XML-utils/man1/ Compile:

Need to get rid of the leading spaces on all lines except the "int fileno" line. Can also forgo the "here doc" and just save the lines between "flex" and "eof" to a file. Run flex on that file. Th

The extra "a" is a typo but would have no effect. The "i" is also superfluous but harmless. Without more details on the "gibberish" it is difficult to guess what happened. The space before "int fileno (

I make most HTTP requests using netcat or similar tcp clients so I write filters that read from stdin. Reading text files with the chunk sizes in hex interspersed is generally easy. Sometimes I do not even bother to remove the chunk sizes

writeall() comes from http://nacl.cace-project.eu and there it is used in a networking program. I removed poll() but only see a very small speed increase so far. fsync() can be removed too but I'm not seeing any resulting
