WSK_CACHE_SD

A WSK application uses the WSK_CACHE_SD client control operation to obtain a cached copy of a security descriptor that can be passed to the WskSocket, WskSocketConnect, and WskControlSocket functions.

To obtain a cached copy of a security descriptor, a WSK application calls the WskControlClient function with the following parameters.

Parameter	Value
ControlCode	WSK_CACHE_SD
InputSize	sizeof(PSECURITY_DESCRIPTOR)
InputBuffer	A pointer to a PSECURITY_DESCRIPTOR-typed variable. This variable contains a pointer to the SECURITY_DESCRIPTOR structure that defines the uncached security descriptor that is being cached.
OutputSize	sizeof(PSECURITY_DESCRIPTOR)
OutputBuffer	A pointer to a PSECURITY_DESCRIPTOR-typed variable. This variable receives a pointer to a SECURITY_DESCRIPTOR structure that describes the cached security descriptor.
OutputSizeReturned	NULL
Irp	NULL

A WSK application must release the cached copy of the security descriptor by using the WSK_RELEASE_SD client control operation when the security descriptor is no longer needed.

See the reference page for the SECURITY_DESCRIPTOR structure for more information.

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