SetClusterResourceDependencyExpression function (clusapi.h)

Specifies the dependency expression to be associated with the resource referred to by hResource. Any existing dependency relationships for the resource will be overwritten. The PCLUSAPI_SET_CLUSTER_RESOURCE_DEPENDENCY_EXPRESSION type defines a pointer to this function.

Syntax

DWORD SetClusterResourceDependencyExpression(
  [in] HRESOURCE hResource,
  [in] LPCWSTR   lpszDependencyExpression
);

Parameters

[in] hResource

Handle to the resource.

[in] lpszDependencyExpression

Address of Unicode string containing the dependency expression.

Return value

ERROR_SUCCESS (0) if successful.

Remarks

The system only supports groups of OR expressions that are combined by using AND. The dependency expressions are described by this BNF grammar.

expression:
      expression_part
    | expression and expression_part

expression_part:
        resource
    | ( or_expression )

or_expression:
        resource
    | or_expression or resource


resource:
    [resourceID]
    | [resourceName]

This gives us expressions of the general form:( [id] or [id] ... ) and ( [id] or [id] ... ) and ...

For example: ([a904e1b7-95dd-47f0-9b2e-f1007d92699b] or [ae6fcf48-c42f-4960-a61a-7f1044067668]) and ([c471abc6-e454-482e-8be4-fae084cf799b] or [de976488-82cb-4950-8ce0-1b45e868e058])
