The IOCTL_STORAGE_LOAD_MEDIA DeviceIoControl operation causes media to be loaded into a device.
dwIoControlCode = IOCTL_STORAGE_LOAD_MEDIA; // operation code lpInBuffer = NULL; // address of input buffer; not used; must be NULL nInBufferSize = 0; // size of input buffer; not used; must be zero lpOutBuffer = NULL; // address of output buffer; not used; must be NULL nOutBufferSize = 0; // size of output buffer; not used; must be zero lpBytesReturned; // address of actual bytes of output
If the operation succeeds, DeviceIoControl returns a nonzero value.
If the operation fails, DeviceIoControl returns a nonzero value. To get extended error information, call GetLastError.
The IOCTL_STORAGE_LOAD_MEDIA is valid only for devices that support loadable media.

Welcome to massmind.org! |
Ashley Roll has put together a really nice little unit here. Leave off the MAX232 and keep these handy for the few times you need true RS232! |
