int seSetLutEntry(int DevID, int Index, BYTE *pEntry)
Description:
Parameters:
Return Value: ERR_OK
int seGetLutEntry(int DevID, int index, BYTE *pEntry)
Description:
Parameters:
Return Value: ERR_OK
int seSetBitsPerPixel(int DevID, UINT BitsPerPixel)
Description:
Parameter:
Return Value: ERR_OK
This routine writes one LUT entry. Unlike seSetLut, the LUT entry indicated by
Index can be any value from 0 to 255.
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.
DevID
Index
pEntry
This routine reads one LUT entry from any index.
DevID
Index
pEntry
This routine sets the system color depth. Valid arguments for BitsPerPixel is are: 1,
2, 4, 8, 15, and 16.
After performing validity checks for the requested color depth the appropriate
registers are changed and the Look-Up Table is set its default value.
This call is similar to a mode set call on a standard VGA.

BitsPerPixel - desired color depth in bits per pixel
ERR_FAILED- possible causes for this error message include:
- registered device ID
- index to LUT entry (0 to 255)
- pointer to an array of three bytes.
- operation completed with no problems
- registered device ID
- index to LUT entry (0 to 255)
- pointer to an array of three bytes
- operation completed with no problems
- registered device ID
- operation completed with no problems
1) attempted to set other than 8 or 15/16 bpp in portrait mode
(portrait mode only supports 8 and 15/16 bpp)
2) factors such as input clock and memory speed will affect the ability
to set some color depths. If the requested color depth cannot be set this
call will fail
