IOCTL_BTH_SDP_SERVICE_SEARCH IOCTL (bthioctl.h)
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
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. |
