[PROJ] How to find the active metadata search path in PROJ 6

[Roger Bivand]

Hi,

I've looked but cannot find the "get" side of 
proj_context_set_search_paths(). Does one exist, or is there an 
alternative way of getting the current active search path?

Reason for question: to be able to add a local directory, for example 
holding grid files downloaded on the fly or caches from previous sessions, 
and where the default data/ directory is not user-writable, I think I need 
to build the ":" or ";" separated list to update the search path. To avoid 
overwriting it, I need to prepend the active search path to the local 
user-writable directory.

Hope this is just something I've missed, a function returning a string, or 
equivalent mechanism.

Roger
