Examples

The following examples show how PROPID_Q_PRIV_LEVELis specified in the MQQUEUEPROPS structure for setting and retrieving the privacy level of the queue.

To set the privacy level

DWORD dwPrivacyLevel = MQ_PRIV_LEVEL_NONE;
aPropID[i] = PROPID_Q_PRIV_LEVEL;        // Property identifier
aVariant[i].vt = VT_UI4;                 // Type indicator
aVariant[i].ulVal = dwPrivacyLevel;      // Privacy level of queue
i++;

To retrieve the privacy level

aPropID[i] = PROPID_Q_PRIV_LEVEL;       // Property identifier
aVariant[i].vt = VT_UI4;                // Type indicator
