The IOCTL_DISK_GET_PARTITION_INFO DeviceIoControl operation returns information about the type, size, and nature of a disk partition.
dwIoControlCode = IOCTL_DISK_GET_PARTITION_INFO ; // 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; // address of output buffer nOutBufferSize; // size of output buffer lpBytesReturned; // address of actual bytes of output
If the operation succeeds, DeviceIoControl returns a nonzero value.
If the operation fails, DeviceIoControl returns zero. To get extended error information, call GetLastError.
This device I/O control operation is for disk devices. Floppy disk drivers, however, do not need to handle this operation.
