Routine Description:
This function is called by the client side DLL to connect with its
server side DLL.
Arguments:
ObjectDirectory - Points to a null terminate string that is the same
as the value of the ObjectDirectory= argument passed to the CSRSS
program.
ServerDllIndex - Index of the server DLL that is being connected to.
It should match one of the ServerDll= arguments passed to the CSRSS
program.
CallbackInformation - An optional pointer to a structure that contains
a pointer to the client callback function dispatch table.
ConnectionInformation - An optional pointer to uninterpreted data.
This data is intended for clients to pass package, version and
protocol identification information to the server to allow the
server to determine if it can satisify the client before
accepting the connection. Upon return to the client, the
ConnectionInformation data block contains any information passed
back from the server DLL by its call to the
CsrCompleteConnection call. The output data overwrites the
input data.
ConnectionInformationLength - Pointer to the length of the
ConnectionInformation data block. The output value is the
length of the data stored in the ConnectionInformation data
block by the server's call to the NtCompleteConnectPort
service. This parameter is OPTIONAL only if the
ConnectionInformation parameter is NULL, otherwise it is
required.
CalledFromServer - On output, TRUE if the dll has been called from
a server process.
Return Value:
Status value.
