void DRV_W25_Close( const DRV_HANDLE handle );Summary
Closes an opened-instance of the W25 driver
Description
This routine closes an opened-instance of the W25 driver, invalidating the handle.

DRV_W25_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_W25_Open DRV_W25_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_W25_Open before the caller may use the driver again.
Usually there is no need for the driver client to verify that the Close operation has completed.
