POSIX?<p>Its quite possible to have a C-based sockets-&#x2F;signals- handler in a single source file, say .. 48k lines of code or so. I&#x27;ve seen many robust system daemons with just such an implementation.<p>3rd party dependencies are definitely an issue that very few languages have managed to promote, since languages either want to promote (or demote) such circumstances as mass-package (i.e. mass usage of the language) in a broad commercial&#x2F;industrial&#x2F;social context.<p>But its not naive to write such things as a Wiki and a Blog in C.  Just .. dangerous.  I imagine there are, however, some good 3rd-party C libraries available to do less-dangerous implementations, however...
