source: tester.c @ 2bc6ad35

release-1.8release-1.9
Last change on this file since 2bc6ad35 was 2bc6ad35, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Add owl_quote_arg and owl_string_append_quoted_arg Also add unit tests. We don't appear to have an equivalent of BarnOwl::quote in C that actually works.
