New Revision: 57723
URL: http://svn.reactos.org/svn/reactos?rev=57723&view=rev
Log:
[KERNEL32/CONSRV]
- Make OpenConsole call only one server api, namely SrvOpenConsole, which was known before
under the name CsrGetHandle (this latter function was removed in r57689 by error).
- Merge CSRSS_GET_INPUT_HANDLE and CSRSS_GET_OUTPUT_HANDLE structures into
CSRSS_OPEN_CONSOLE (used by the functions named above).
[CONSRV]
- Add SrvOpenConsole (copied from CsrGetHandle), and add DPRINT1s to it.
- Load the localized string "Command Prompt" using the Server DLL's instance
handle instead of calling GetModuleHandleW.
- Make use of CONSOLE_PROCESS_DATA structures.
