6765 + The host controller must check the card response to determine whether it
6766 + is safe to perform a data transfer. This API only checks commands that
6767 + involve data transfers and checks various status fields in the command response.
6768 + If the card cannot accept data, this function will return a non-successful status that
6769 + should be treated as a request failure. The host driver should complete the request with the
6770 + returned status. Host controller should only call this function in preparation for a

6772 + if (CheckMode == SDHCD_CHECK_SPI_TOKEN) :
6773 + This API checks the SPI token and returns a timeout status if the illegal command bit is
6774 + set. This simulates the behavior of SD 1/4 bit operation where illegal commands result in
6775 + a command timeout. A driver that supports SPI mode should pass every response to this
6776 + function to determine the appropriate error status to complete the request with. If the
6777 + API returns success, the response indicates that the card accepted the command.
6778 +
6779 + @example: Checking the response before starting the data transfer :
6780 + if (SDIO_SUCCESS(status) && (pReq->Flags & SDREQ_FLAGS_DATA_TRANS)) {

9093 + @notes: This function creates a simple first-in-first-out message queue. The caller must determine
9094 + the maximum number of messages the queue supports and the size of each message. This
9095 + function will pre-allocate memory for each message. A producer of data posts a message
9096 + using SDLIB_PostMessage with a user defined data structure. A consumer of this data
9097 + can retrieve the message (in FIFO order) using SDLIB_GetMessage. A message queue does not
9098 + provide a signaling mechanism for notifying a consumer of data. Notifying a consumer is
9099 + user defined.
