Parameters:
Return Value: ERR_OK
int seReadDisplayWord(int DevID, DWORD Offset, WORD *pWord)
Description:
Parameters:
Return Value: ERR_OK
int seReadDisplayDword(int DevID, DWORD Offset, DWORD *pDword)
Description:
Parameters:
Return Value: ERR_OK
The functions in the Color Manipulation section deal with altering the color values in the
Look-Up Table directly through the accessor functions and indirectly through the color
depth setting functions.
int seSetLut(int DevID, BYTE *pLut, int Count)
Description:
Parameters:
DevID
Offset
pByte
ERR_HAL_BAD_ARG - if the value for Offset is greater than the amount of
Reads a word from the display buffer at the specified offset and returns the value in
pWord.
DevID
Offset
pWord
ERR_HAL_BAD_ARG - if the value for Offset is greater than the amount of
Reads a dword from the display buffer at the specified offset and returns the value
in pDword.
DevID

pDword
ERR_HAL_BAD_ARG - if the value for Offset is greater than the amount of
This routine can write one or more LUT entries. The writes always start with Look-
Up Table index 0 and continue for Count entries.
A Look-Up Table entry consists of three bytes, one each for Red, Green, and Blue.
The color information is stored in the four most significant bits of each byte.
