Required Entry Points for Stream Interface Driver DLLs

For every stream interface driver DLL, the required entry points implement standard file I/O functions plus power management functions used by the Windows CE kernel. The following table shows the required entry points.

XXX_Close XXX_Deinit
XXX_Init XXX_IOControl
XXX_Open XXX_PowerDown
XXX_PowerUp XXX_Read
XXX_Seek XXX_Write

When you create a DLL, replace XXX in the entry-point names with a device file name prefix. For more information, see Device File Name Prefixes.
