PanelView Plus CE-Specific Extensions to the WinCE API 43

Remarks:

The functions use a model that is similar to device IOCTLs. Functions

take a parameter, the size of data, and a generic buffer. The contents

of the buffer depend on the parameter. The actual size of data that is

Set/Get is returned along with a return code and data.

DWORDrm_Get/SetParameter(DWORD dwParameter, DWORD

*dwSize,VOID *pvData);

The *dwSize parameter passed in indicates the space available in

pvData for a Get or the space of valid data to use for a Set. Upon

success, *dwSize is returned containing the actual amount of data

returned in the buffer for a Get, or the amount of data from the buffer

used for a Set.

The pvData must point to a buffer of large enough size and of correct

size. Parameters which use *pvData as aligned types (e.g. as pointing

to a DWORD or a pointer) must follow the alignment restrictions of

these types. For example, if getting a parameter where *pvData will be

filled with a DWORD value, pvData must be DWORD aligned.

• RM_PARAMETER_DISABLE_USER_INPUT

This parameter prohibits user input via the touchscreen,

keypad and keyboard. This parameter permits an application

to immediately disable user input when the display is lost due

to a back light failure.
