Routine Description:
|
|||
|
|
|||
|
If the caller supplies an SD this validates and makes a copy of the
|
|||
|
security descriptor. Otherwise is generates a good default SD.
|
|||
|
|
|||
|
Arguments:
|
|||
|
|
|||
|
ThisAddress - Supplies the address which will own the security descriptor.
|
|||
|
|
|||
|
SecurityDescriptor - Supplies the security descriptor to be copied.
|
|||
|
|
|||
|
Return Value:
|
|||
|
|
|||
|
RPC_S_OK - Everyone is happy; we successfully duplicated the security
|
|||
|
descriptor.
|
|||
|
|
|||
|
RPC_S_INVALID_SECURITY_DESC - The supplied security descriptor is invalid.
|
|||
|
|
|||
|
RPC_S_OUT_OF_MEMORY - Insufficient memory is available to duplicate the
|

|
security descriptor.

|
|

|
Sends a message on the connection. This method must appear

|
to be synchronous from the callers perspective.
|

|
|

|
Arguments:
|
|||
|
|
|||
|
pConnection - The connection.
|
|||
|
Buffer - The data to send.
|
|||
|
BufferLength - The size of the buffer.
|
|||
|
fDisableShutdownCheck - N/A to named pipes.
|
|||
|
|
|||
|
Return Value:
|
|||
|
|
|||
|
RPC_S_OK - Data sent
|
|||
|
RPC_P_SEND_FAILED - Connection will be aborted if this is returned.
|

Routine Description:
|
|||
|
|
|||
|
Sends a request to the server and waits to receive the next PDU
|
|||
|
to arrive at the connection.
|
|||
|
|
|||
|
Arguments:
|
|||
|
|
|||
|
ThisConnection - The connection to wait on.
|
|||
|
InputBufferSize - The size of the data to send to the server.
|
|||
|
InputBuffer - The data to send to the server
|
|||
|
pOutputBufferSize - On return it contains the size of the PDU received.
|
|||
|
pOutputBuffer - On return contains the PDU received.
|
|||
|
|
|||
|
Return Value:
|
|||
|
|
|||
|
RPC_S_OK
|
|||
|
|
|||
|
RPC_P_SEND_FAILED - Connection aborted, data did not reach the server.
|
|||
|
RPC_P_RECEIVE_FAILED - Connection aborted, data might have reached
|
|||
|
the server.
