Detailed Description

Portable macros for compiler attributes.

Working with many different compilers often requires using different statements for this like attributes (deprecation, visibility) and pragmas (suppressing external warnings)

To help developers use these features without needing to know the exact compiler constructs, datatools supplies preprocessor macros that expand to the required construct for the compiler in use.
