Objet : Getting Proj information after pj_init has been thrown


Hi all and a very happy new year to anyone.

We’re using proj.4 as API and are quite happy with it.

So, our base reference is the proj_api.h header.

Is there any way to retrieve PJ information (like major axis or any other
projection information) after a pj_init() has been called?

We did try to use projects.h in place of proj_api.h but this brings us to
compilation nightmare since this one ‘typedef’s a PVALUE that winreg.h is
also ‘typedef’ying (we’re using M$ platform as you may have understood).

Any help in that manner would be welcome.
