New Revision: 34685
URL: http://svn.reactos.org/svn/reactos?rev=34685&view=rev
Log:
- Implement access masks and optional inheritability for console handles. Currently, only
CsrDuplicateHandle actually checks the access mask.
- CreateFileW: Pass CONIN$/CONOUT$ opens to OpenConsoleW.
- DuplicateConsoleHandle: Remove ProcessId from request structure, since console handles
can only be duplicated in the calling process.
Don't check low bits of handle (Windows ignores them), but
do check options and (if DUPLICATE_SAME_ACCESS is not specified) access mode.
- OpenConsoleW: Make wsName parameter const; allow any combination of GENERIC_READ and
GENERIC_WRITE, don't require both.
- CreateConsoleScreenBuffer: Add parameter checks; return INVALID_HANDLE_VALUE (not FALSE)
on failure.
- Remove remnants of unnecessary handle in Get/SetConsoleTitle.
- CsrDuplicateHandle: Implement DUPLICATE_CLOSE_SOURCE and DUPLICATE_SAME_ACCESS options.
