+
+ @notes: This procedure can be called to issue an I/O abort request to an I/O function.
+ This procedure cannot be used to abort a data (block) transfer already in progress.
+ It is intended to be used when a data (block) transfer completes with an error and only if
+ the I/O function requires an abort action. Some I/O functions may automatically
+ recover from such failures and not require this action. This function issues
+ the abort command synchronously and can potentially block.
+ If an async request is required, you must allocate a request and use
+ SDLIB_SetupIOAbortAsync() to prepare the request.
+
+ @example: Issuing I/O Abort synchronously :
+ .. check status from last block operation:
+ if (status == SDIO_STATUS_BUS_READ_TIMEOUT) {
+ .. on failure, issue I/O abort
+ status2 = SDLIB_IssueIOAbort(pDevice);
+ }
+ Issuing I/O Abort asynchronously:
+ ... allocate a request
+ ... setup the request:
+ SDLIB_SetupIOAbortAsync(pDevice,pReq);
+ pReq->pCompletion = myIOAbortCompletion;
+ pReq->pCompleteContext = pDevice;
+ status = SDDEVICE_CALL_REQUEST_FUNC(pDevice,pReq);
