-- v7: win32u: Read window dpi_context from the shared memory. win32u: Pass id and offset separately to find_shared_session_object. server: Move window dpi_context to the shared memory. server: Allocate shared memory objects for windows. win32u: Remove unnecessary shared object lock reset. server: Fix shared object offset when additional blocks are allocated.
From: Rémi Bernon rbernon@codeweavers.com
The shared object offset is an absolute offset from the start of the session shared memory file, as it is used to identify the corresponding mmapped block on the client side. --- server/mapping.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
