The GetSystemPaletteEntries function retrieves a range of palette entries from the system palette that is associated with the specified device context.
UINT GetSystemPaletteEntries(
| HDC hdc, | // handle of device context |
| UINT iStartIndex, | // index of first entry to be retrieved |
| UINT nEntries, | // number of entries to be retrieved |
| LPPALETTEENTRY lppe | // array receiving system-palette entries |
| ); |
Parameters
hdc
Identifies the device context.
iStartIndex
Specifies the first entry to be retrieved from the system palette.
nEntries
Specifies the number of entries to be retrieved from the system palette.
lppe
Points to an array of PALETTEENTRY structures to receive the palette entries. The array must contain at least as many structures as specified by the nEntries parameter. If this parameter is NULL, the function returns the total number of entries in the palette.
Return Values
If the function succeeds, the return value is the number of entries retrieved from the palette.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
An application can determine whether a device supports palette operations by calling the GetDeviceCaps function and specifying the RASTERCAPS constant.
