           Summary: libclang API to access CXCodeCompleteResults and
                    CXCompletionResult structures

There are no API to access CXCodeCompleteResults structure to get
CXCompletionResult and unsigned NumResults.
The same situation with CXCompletionResult structure (e.g. CXCursorKind
CursorKind, CXCompletionString CompletionString). They used inside
clang_sortCodeCompletionResults, clang_getCompletionChunkKind,
clang_getCompletionChunkText, clang_getCompletionChunkCompletionString,
clang_getNumCompletionChunks, etc. functions.

Currently, it possible to get them directly only, e.g.:
//...

CXIndex idx = clang_createIndex(NULL, NULL);
CXTranslationUnit tu = clang_createTranslationUnit(idx, ast_filename);
CXCodeCompleteResults *rs = clang_codeCompleteAt(tu, complete_filename,
complete_line, complete_column, unsaved_files, num_unsaved_files, options);
clang_sortCodeCompletionResults(rs->Results, rs->NumResults);

for (unsigned i = 0, n = rs->NumResults; i < n; ++i) {
    CXCompletionResult r = rs->Results[i];
    CXCursorKind kind = r.CursorKind;
    CXCompletionString cs = r.CompletionString;

    for (unsigned j = 0, m = clang_getNumCompletionChunks(cs); j < m; ++j) {
        CXString text = clang_getCompletionChunkText(cs, j);
        printf("%d: %s\n", i, text);
        clang_disposeString(text);
    }
}
