IeXdi2Generic::GetErrorDescription (Windows CE 5.0)
This method returns a text description of an eXDI service error code.
HRESULT GetErrorDescription( HRESULT ErrorCode, SHORT wLangLocalId, LPOLESTR* pszErrorDescBOOL* pfRetryAvail);
Parameters
- ErrorCode
[in] Error code returned from a previous call. - wLangLocalId
[in] Language LocaleId that supports multiple languages on the client device. - pszErrorDesc
[out] Pointer to the textual description of the nonstandard error. The buffer for this value is allocated by CoTaskMemAlloc. - pfRetryAvail
[out] If TRUE, indicates the error can be retried.
Return Values
The following table shows return values for this method.
| Value | Description |
|---|---|
| S_OK | Indicates the function was successful. |
| E_FAIL | Indicates an unspecified failure. |
| E_NOTIMPL | Indicates the error code is not implemented. |
| E_INVALIDARG | Indicates one or more invalid arguments. |
| EXDI_E_COMMUNICATION | Indicates a communication error between host driver and debugging target. |
Remarks
To avoid resource leaking, use CoTaskMemFree to free the task memory used by the buffers that this function uses to return values for pszErrorDesc and pfRetryAvail.
The following example shows how you might use CoTaskMemFree to release the memory held for the return buffers.
WORD wLang = 0x0409
LPOLESTR pszErrorDesc;
BOOL pfRetryAvail;
HRESULT hr = pieXdi2Generic->GetErrorDescription (hrErrorCode,
wLang, &pszErrorDesc, &pfRetryAvail);
if (SUCCEEDED (hr))
{
// Use error description.
CoTaskMemFree (pszErrorDesc);
pszErrorDesc = 0;
}
