)

Parameters

branch

The fully qualified name of the branch to be browsed

maxElements

The method must not return any more elements than this value. If the server supports Continuation Points, then the Server may return a Continuation Point at a value less than dwMaxElementsReturned. If the server does not support Continuation Points, and more than dwMaxElementsReturned are available, then the Server shall return the first dwMaxElementsReturned elements and set the pbMoreElements parameter to TRUE. If dwMaxElementsReturned is 0 then there is no client side restriction on the number of returned elements.

browseType

An OPCV3BrowseType enumeration value {All, Branch, Item} specifying which subset of browse elements to return.

nameFilter

A wildcard string that conforms to the Visual Basic LIKE operator, which will be used to filter Element names. A NUL String implies no filter.

vendorFilter

A server specific filter string. This is entirely free format and may be entered by the user via an EDIT field. A pointer to a NUL string indicates no filtering.

continuationPoint

If this is a secondary call to Browse, the previous call might have returned a Continuation Point where the Browse can restart from. Clients must pass a NUL string in the initial call to Browse. This is an opaque value, which the server creates. A Continuation Point will be returned if a Server does support Continuation Point, and the reply is larger than dwMaxElementsReturned. The Continuation Point will allow the Client to resume the Browse from the previous completion point.
The continuationPoint is also used to indicate if there are more elements than the maxElements parameter allows to be returned in this call. If there are more elements then continuationPoint must be set to NULL. Otherwise it is set to "" (an empty string) if exactly all elements could be returned or to an implementation specific string for an actual continuation point.

numNodes

OUT: Number of nodes returned

nodes

OUT: Array of BrowseNodeInfo objects with the information of the browsed nodes.

Return Value

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
