I see. Would it be possible then to define a second function within the DLL, let's say freeStr(const char* resStr) which releases the memory
again?

And should Troy Noble's code then work for strings > 64 KB, too? (Currently, I get an access violation, even when not freeing the allocated
memory outside the DLL.)

char*
mallocAndStrCpy (const char* srcStr) {
   if (srcStr == NULL)
      return NULL;
   return strdup(srcStr);
}
