My USB driver code is such that user can write data to device using WriteFile as well as by passing IOCTL_BULK_WRITE in DeviceIoControl. I am planning to expose only one kind of interface to the user for writing to device. Please suggest which will be a better option and why ?
Outside of file systems, ReadFile/WriteFile is a bit of a rarity. Typically drivers use IOCTLs for the same purposes b/c you can add more contextual information (since you have 2 buffers) and you can use a different IOCTL value to do a different type of read/write than another IOCTL.
