Here you will find additional information about the RxSDK objects and their usage.
Appendix A: Return Values
The COM objects expose one or more interfaces each. All methods defined by these interfaces return an HRESULT status value to inform the client about the success or failure of the requested operation.
Currently, the RxSDK objects return the following standard HRESULT values:
| Name | Description | Value |
|---|---|---|
| S_OK | Operation successful | 0x00000000 |
| S_FALSE | Operation successful, but may have been void | 0x00000001 |
| E_UNEXPECTED | Unexpected failure | 0x8000FFFF |
| E_NOTIMPL | Not implemented | 0x80004001 |
| E_OUTOFMEMORY | Failed to allocate necessary memory | 0x8007000E |
| E_INVALIDARG | One or more arguments are invalid | 0x80070057 |
| E_NOINTERFACE | No such interface supported | 0x80004002 |
| E_POINTER | Invalid pointer | 0x80004003 |
| E_HANDLE | Invalid handle | 0x80070006 |
| E_ABORT | Operation aborted | 0x80004004 |
| E_FAIL | Unspecified failure | 0x80004005 |
| E_ACCESSDENIED | General access denied error | 0x80070005 |
