Subject: [Rd] dotcode typo?
I ran across the following in the R-2.0.1 source, src/main/dotcode.c, in the
function resolveNativeRoutine(), lines 146-163. Line 152 looks like a typo:
here are lines 149-155
if(!*fun) {
if(dll.type != FILENAME) {
*fun = R_FindNativeSymbolFromDLL(buf, &dll, symbol);
if(!fun) {
errorcall(call, "cannot resolve native routine");
}
}
and I think the "if(!fun)" should be "if(!*fun)".
I think you're right about the typo.
In the current code, !fun is known to be false, so the "cannot resolve
native routine" error message is not even compiled in. Putting in !*fun
means that
.C("foo")
produces "cannot resolve native routine", rather than "function name not
in load table" from the test a few lines down.
I'll commit this change after testing, but I hope Duncan TL has time to
look at it and make sure the logic is okay.
