New Revision: 55478
URL: http://svn.reactos.org/svn/reactos?rev=55478&view=rev
Log:
[SMSS2]: Implement executing the initial command as well as doing the SM-to-SM initial
connection.
[SMSS2]: Implement the main LPC loop and handle all the supported APIs (all stubs for
now). Also handle new connection requests and implement SmpHandleConnectionRequest.
[SMSS2]: Implement subsystem helper functions.
[SMSS2]: Use SmApiPort2 instead of Sm2ApiPort.
[SMSS2]: Rename the SMSRV_APIs not to conflict with the function names, nor with the
client functions in smlib.
