Bluetooth and BLOB

Bluetooth and BLOB

Bluetooth uses the BLOB structure to pass or receive transport-specific data to the WSAQUERYSET structure during calls to theWSASetService or WSALookupService* functions.

For use with Bluetooth and the WSASetService function, the BLOB structure members are required to have the following settings:

• The cbsize member must be set to the size of the BTH_SET_SERVICE structure used in the pBlobData member, in bytes.
• The pBlobData member must be a pointer to a BTH_SET_SERVICE structure.

For use with Bluetooth and WSALookupServiceBegin for Device Inquiry, use the following settings:

• The cbsize member must be set to the size of the BTH_QUERY_DEVICE structure used in the pBlobData member, in bytes.
• The pBlobData member must be a pointer to a BTH_QUERY_DEVICE structure.

For use with Bluetooth and WSALookupServiceBegin for Service Discovery, use the following settings:

• The cbsize member must be set to the size of the BTH_QUERY_SERVICE structure used in the pBlobData member, in bytes.
• The pBlobData member must be a pointer to a BTH_QUERY_SERVICE structure.

For more information, see the Remarks section in the BTH_SET_SERVICE structure reference page.
