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.
