SubnetMask
Describes the subnet mask to be applied for routing for the IP address. The following table summarizes the attributes of the SubnetMask property.
| Attribute | Value |
|---|---|
| Data type | Null-terminated Unicode string |
| Access | Read/write |
| Status | Required |
| Structure | CLUSPROP_SZ |
| Maximum | None (but see Maximum Property Size.) |
| Default | NULL |
Remarks
The data in the SubnetMask property must be formatted as xxx.xxx.xxx.xxx where xxx represents a decimal number between 0 and 255. The value 255.255.255.255 is not valid.
The CLUSPROP_SZ_DECLARE macro creates a CLUSPROP_SZ structure with an array of the correct size.
Examples
The property value portion of a property list entry for SubnetMask can be set with the following example code.
WCHAR szSubnetMaskData[] = L"255.255.0.0";
CLUSPROP_SZ_DECLARE( SubnetMaskValue,
sizeof( szSubnetMaskData ) / sizeof( WCHAR ) );
SubnetMaskValue.Syntax.dw = CLUSPROP_SYNTAX_LIST_VALUE_SZ;
SubnetMaskValue.cbLength = sizeof( szSubnetMaskData );
StringCbCopy( SubnetMaskValue.sz,
SubnetMaskValue.cbLength,
szSubnetMaskData );
