..\HARDWARE\SDff\SDff.c(131): error:  #167: argument of type "uint8_t" is incompatible with parameter of type "const void *"

Code:
void writeFile(uint8_t *str)
{
    res = f_open(&fsrc, "0:/longfilenametest.txt", FA_OPEN_ALWAYS | FA_WRITE);
    if(res != FR_OK)
    {
        printf("open file error : %d\n\r",res);
    }
    else
    {
       res = f_write(&fsrc, *str, sizeof(*str), &bw);   /* Write it to the dst file */
        if(res == FR_OK)
        {
            printf("write data ok! %d\n\r",bw);
        }
        else
        {
            printf("write data error : %d\n\r",res);
        }
        f_close(&fsrc);
    }
}
