SdpCreateNodeUrl function (sdplib.h)

Article
02/22/2024

The Bluetooth SdpCreateNodeUrl function is used to allocate and initialize an SDP_NODE structure to a URL type.

Syntax

PSDP_NODE SdpCreateNodeUrl(
  [in] PCHAR url,
       ULONG urlLength,
  [in] ULONG tag
);

Parameters

[in] url

A pointer to the URL value that is used to initialize the SDP_NODE structure.

urlLength

An unsigned long integer value that holds the length of the URL.

[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 SdpCreateNodeUrl 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 SdpCreateNodeUrl 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.
