The required entry points in any installable device driver DLL are those which implement the standard Win32 file I/O functions, plus the power management functions used by the Windows CE kernel. The entry points are:
| xxx_Close | xxx_Deinit |
| xxx_Init | xxx_IOControl |
| xxx_Open | xxx_PowerDown |
| xxx_PowerUp | xxx_Read |
| xxx_Seek | xxx_Write |
Recall that you must replace "xxx" in the entry point names with the Device Filename Prefix for your installable device driver.
For details about these entry points, see Stream I/O Functions and Required Entry Points.
