How to query DCMTK version

[kingcrimson-biubiu]

Dear forum,
May I know if there's a function in DCMTK that can return the API version (such as "3.6.3")? I searched the source repository in the 3.6.3 branch but didn't manage to find one. Thank you!

There is a macro OFFIS_DCMTK_VERSION in "dcmtk/dcmdata/dcuid.h".

Thanks for your reply, J. Riesmeier.

It appears that OFFIS_DCMTK_VERSION is an alias to PACKAGE_VERSION_SUFFIX, which is defined in dcmtk/config/osconfig.h

My 2 cents: It would be more convenient to users if, instead of being a preprocessor macro alone, the version number is made a return value of an API global function (say std::string GetVersionString()). It would also be helpful if it is accessible in CMake (say DCMTK_VERSION).

No, OFFIS_DCMTK_VERSION is defined as a concatenation of PACKAGE_VERSION and PACKAGE_VERSION_SUFFIX, e.g. "3.6.3+"

... the version number is made a return value of an API global function (say std::string GetVersionString()). It would also be helpful if it is accessible in CMake (say DCMTK_VERSION).

I am not a friend of global functions but what would be the advantage compared to a preprocessor macro; is it type safety?
What is wrong with the CMake variable DCMTK_PACKAGE_VERSION?
