WSK_TRANSPORT_LIST_QUERY

A WSK application uses the WSK_TRANSPORT_LIST_QUERY client control operation to retrieve a list of available network transports that can be specified when creating a new socket.

To retrieve a list of available network transports, a WSK application calls the WskControlClient function with the following parameters.

Parameter	Value
ControlCode	WSK_TRANSPORT_LIST_QUERY
InputSize	0
InputBuffer	NULL
OutputSize	The size, in bytes, of the array of structures that is pointed to by the OutputBuffer parameter
OutputBuffer	A pointer to an array of WSK_TRANSPORT structures that receives the list of available network transports
OutputSizeReturned	A pointer to a SIZE_T-typed variable that receives the number of bytes of data that are copied into the array of structures that is pointed to by the OutputBuffer parameter
Irp	NULL

A WSK application can specify zero in the OutputSize parameter and NULL in the OutputBuffer parameter to determine the size of the array of WSK_TRANSPORT structures, in bytes, that is required to contain the complete list of available network transports. In such a situation, the call to the WskControlClient function returns STATUS_BUFFER_OVERFLOW, and the variable that is pointed to by the OutputSizeReturned parameter contains the required buffer size. The application can then allocate a buffer that is large enough to contain the complete list of available network transports and can call the WskControlClient function a second time, specifying the parameters that are shown in the preceding table.

The Irp parameter must be NULL for this client control operation.
