This is the shared-memory for "ir:USER", which is provided by the application via InitializeIrnop or InitializeIrnopShared. The size of the shared memory is determined by parameters of the Init functions above.
Overall Structure
The shared memory consists of 2 or 5 components, depending on which Init function is called. For InitializeIrnopShared, ir service puts more information to the shared memory and applications can read it directly; for InitializeIrnop, ir service puts less information and store the rest in its local storage. All these components are adjacent to each other.
| Size | Description |
|---|---|
| 0x10 | StatusInfo. Only presents when InitializeIrnopShared is called |
| 0x10 | ReceiveBufferInfo. Only presents when InitializeIrnopShared is called |
| (specified by Init paramter) | ReceiveBuffer |
| 0x10 | SendBufferInfo. Only presents when InitializeIrnopShared is called |
| (specified by Init paramter) | SendBuffer |
