mdlLinkage_appendUsingDescr 오류

mdlLinkage_appendUsingDescr 호출 실패 때문에 미치겠습니다.
다른 프로젝트와 똑 같이 했는데 왜 실패하는지?

mdlCell_create(&groupCell, pToken1->buf[2], NULL, FALSE);
mdlElmdscr_new(&chainDscrP,NULL,&groupCell);
addUserData(&chainDscrP , filePos); //! mdlLinkage_appendUsingDescr 호출
filePos = mdlElmdscr_add(chainDscrP);

Private int addUserData( MSElementDescr **elP , ULong filePos )
{
    int   status;
    char  cMsg[100];
    char  linkString[MAXFILELENGTH];
    LinkageHeader   linkHdr;

    memset(&linkHdr, '\0' , sizeof(LinkageHeader));
    linkHdr.info  =0;
    linkHdr.remote  =0;
    linkHdr.modified =0;
    linkHdr.user  =1;
    linkHdr.class  =0;
    linkHdr.words;
    linkHdr.primaryID = 901;

    memset(&linkInfo , '\0' , sizeof(LinkInfo));
    strcpy(linkInfo.tag_Name1 , "hello");
    status = mdlLinkage_appendUsingDescr(
        elP,
        &linkHdr,
        &linkInfo,
        RSCID_DataDef_Link,
        NULL,
        FALSE);

    if (status == SUCCESS )
    {        
    }
    else
    {
        PrintError ("\nError adding user data!");
    }

    return (status == SUCCESS) ? MODIFY_STATUS_REPLACE : MODIFY_STATUS_ABORT; 
}
