Subject: secnet.h: provide helpful STRING macro (for preprocessor stringification)
X-Git-Tag: v0.2.0~30
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=45cfab8ca7db61ce4677e2e77e76b9266c57ab12;p=secnet.git

secnet.h: provide helpful STRING macro (for preprocessor stringification)

Uses preprocessor stringification; can be helpful for rendering
compile-time constants (eg compile time limit macros) for messages,
etc.

Not used yet; will be used later in this series.
