Suggestion: mkString(NULL) should be NA
...some kind if they got NULL, no?
Not necessarily. A char* of NULL can be a string which is not
initiated or simply unavailable due to configuration.
The example from my original email was in curl package which exposes
the version string of libz that was used to build libcurl:
mkString(data->libz_version)
This worked on all platforms that I tested. However a user found that
if libcurl was configured --without-libz (which is uncommon) the
libz_version string does not get set by libcurl and is always NULL. I
had not foreseen this and it would lead to a segfault.
I think making mkString() return NA...
