Examples
LinkarClt lkClt = new LinkarClt();
CredentialsOptions crdOpt = new CredentialsOptions("127.0.0.1", 11300, "admin", "admin", "ENTRYPOINT");
lkClt.Login(crdOpt);

string filename = "LK.CUSTOMERS";
string recordId = "1";
string inputData = "..."; // Buffer with the content of record to be update
UpdateOptions updateOptions = new UpdateOptions();
string originalRecord = ""; // Buffer with the original record content (only necessary for use with optimistic lock control)
DATAFORMAT_TYPE inputStringType = DATAFORMAT_TYPE.MV;
DATAFORMAT_TYPE outputStringType = DATAFORMAT_TYPE.MV;

lkClt.UpdateAsync_Text(new LinkarClt.OperationAsyncCallbackString(UpdateAsyncFinished), filename, recordId, inputData, updateOptions, originalRecord, inputStringType, outputStringType);
