spi_getdrvinfo()

The spi_getdrvinfo() function gets the driver information for the low-level module. The prototype for this function is:

int spi_getdrvinfo( int fd,
                    spi_drvinfo_t *drvinfo );

The arguments are:

fd
The file descriptor returned by spi_open().
devinfo
A pointer to device information structure:
typedef struct {
    uint32_t    version;
    char        name[16];   /* Driver name */
    uint32_t    feature;
} spi_drvinfo_t;
  

The function returns EOK if the driver information is obtained successfully.
