IOCTL_BTH_SDP_SERVICE_SEARCH IOCTL

The IOCTL_BTH_SDP_SERVICE_SEARCH request contacts a remote device with an SDP request for handles to SDP records of a particular service class or classes.

Major Code

IRP_MJ_DEVICE_CONTROL

Input Buffer

The AssociatedIrp.SystemBuffer member contains a BTH_SDP_SERVICE_SEARCH_REQUEST structure that specifies the connection handle to the remote SDP server and an array of GUIDs to search for.

Input Buffer Length

The length of a BTH_SDP_SERVICE_SEARCH_REQUEST structure/

Output Buffer

The AssociatedIrp.SystemBuffer member points to a buffer that contains a variable length array of unsigned long integer values. Each value represents a remote SDP service record.

Output Buffer Length

Callers can determine the length of this array by dividing the Information member of the STATUS_BLOCK structure by sizeof(ULONG).

Status Block

If the request is successful, the Information member of the STATUS_BLOCK structure is set to the size, in bytes, of the output buffer. Otherwise, the Information member is set to zero.

The Status member is set to one of values in the following table.

Status value Description
STATUS_SUCCESS The IOCTL completed successfully.
STATUS_DEVICE_NOT_CONNECTED The device on which the SDP service resides was not connected.
STATUS_INSUFFICIENT_RESOURCES There was not enough memory to complete this operation.
STATUS_INVALID_BUFFER_SIZE The output buffer was sized incorrectly.
STATUS_INVALID_PARAMETER One of the values in the input buffer was not valid.
STATUS_REQUEST_NOT_ACCEPTED The SDP service rejected the request.
STATUS_TOO_MANY_GUIDS_REQUESTED The SDP service could not process the number of GUIDs passed in the input buffer.
