1.1.6.4.5 DRV_SDMMC_Close Function
C
void DRV_SDMMC_Close ( DRV_HANDLE handle );
Summary
Closes an opened-instance of the SD Card driver.
Description
This routine closes an opened-instance of the SD Card driver, invalidating the handle.
Precondition
The DRV_SDMMC_Initialize routine must have been called for the specified SD Card driver instance.
DRV_SDMMC_Open must have been called to obtain a valid opened device handle.
Parameters
| Param | Description |
|---|---|
| handle | A valid open-instance handle, returned from the driver's open routine |
Returns
None
Example
DRV_HANDLE handle; // Returned from DRV_SDMMC_Open DRV_SDMMC_Close (handle);
Remarks
After calling this routine, the handle passed in "handle" must not be used with any of the remaining driver routines. A new handle must be obtained by calling DRV_SDMMC_Open before the caller may use the driver again.
If any requests were queued by the client, the driver will remove those requests from the queue and issue a DRV_SDMMC_EVENT_COMMAND_ERROR event, (if an event handler is registered by the client) before the client is closed.
