XvioPostMessage function

Sends a message (asynchronously) to the target partition. The message is then handled by an XVIO context within one of the remote partition's drivers.

Syntax

C++

NTSTATUS XvioPostMessage(
    uint32_t TargetContextId,
    uint64_t TargetPartition,
    uint64_t MessageCode,
    uint16_t DataSize,
    void* Data
);

Parameters

uint32_t TargetContextId
The context ID of the target XVIO instance (pretty much the target driver) on the target partition.

uint64_t TargetPartition
Pretty self-explanatory, the partition the message is targeted to, be it HostOS, SystemOS or GameOS. See Partition IDs for more details.

uint64_t MessageCode
The code that is being posted, practically designating the action to be performed by the target.

uint16_t DataSize
Specifies the size of the Data buffer in bytes, with a maximum of 232 bytes total -- can be 0.

void* Data
Pointer to the data to be sent to the target -- can be NULL.

Return value

Returns your standard NTSTATUS with some extra XVIO statuses added on top (will document these soon)
