The following sample populates a resbuf with key column names using ade_keycolumnlist(). The contents of the resbuf are displayed and the resbuf is released as required.

char* pszLinkTemplate = "BlockGroup";
struct resbuf* pKeyColumnListRb = ade_keycolumnlist(pszLinkTemplate);
if (NULL != pKeyColumnListRb) {
    struct resbuf* rb = pKeyColumnListRb;
    while(rb != NULL) {
        acutPrintf(
            "\nThe Key column name(s) are: %s"
            , rb->resval.rstring);
        rb = rb->rbnext;
    }
}
else {
    acutPrintf(
        "\nThere are no specified link templates in this project.");
}
acutRelRb(pKeyColumnListRb);
