The usernames can be Citect or Windows users.
VerifyPrivilegeTagWrite(sTagName, sValueToWrite, sLogDevice, sAccess, sGlobalPriv, sPriv1, sPriv2, sPriv3, sPriv4, sPriv5, sPriv6, sPriv7, sPriv8)
The name of the tag to which a write needs to be approved.

The name of a log device if logging is required, otherwise pass an empty string.
The required user viewable areas, or pass an empty string for none.

// This example generates a form to request a user to approve the tag write operation.
// This user needs privilege levels of 6 and 3.

// is set to indicate the approval status.
