The Bluetooth SdpCreateNodeUInt32 function is used to allocate and initialize an SDP_NODE structure to an unsigned 32-bit integer type.
Syntax
PSDP_NODE SdpCreateNodeUInt32(
[in] ULONG ulVal,
[in] ULONG tag
);
Parameters
[in] ulVal
The unsigned 32-bit integer value that is used to initialize the SDP_NODE structure.
[in] tag
A profile driver defined tag to associate with the node.
Return value
If successful, this function returns a pointer to the newly allocated SDP_NODE structure. If not successful, this function returns NULL.
Remarks
After the SdpCreateNodeUInt32 function allocates an SDP_NODE structure, it initializes the structure in the following ways.
It ensures that the SDP_NODE structure's data type and data size fields are set appropriately.
It ensures that the pointer members of the associated SDP_NODE_HEADER structure are initialized to point to the node itself. This creates a valid list with only one element.
It ensures that the value parameter passed to the function is copied to the appropriate element of the SDP_NODE_DATA union that is associated with the SDP_NODE structure.
The data associated with the SdpCreateNodeUInt32 function is copied into the node, and the original data can be freed at any time.
Bluetooth profile drivers can obtain a pointer to this function through the BTHDDI_SDP_NODE_INTERFACE structure.
