View source for GreDeviceSetPaletteEntries

GreDeviceSetPaletteEntries changes the entries in a palette as a result of an application's [[GpiSetPaletteEntries]] request. These changes do not become apparent until an application calls [[WinRealizePalette]]. If an application wants to change its palette rapidly and makes those changes immediately apparent, it calls [[GpiAnimatePalette]].

This function can be hooked by the presentation driver.

;Simulation support: This function is simulated by a handling routine in Revision 2.0 (or later) of the graphics engine.

== Syntax == 
 GreDeviceSetPaletteEntries(hdc, hdevpal, ulFormat, ulStart, cclr, pclr, pInstance, lFunction)

== Parameters ==
;hdc (HDC) - input:Device context handle.
;hdevpal (ULONG) - input:Device palette handle.
;ulFormat (ULONG) - input:Specifies the entry format. Must be LCOLF_CONSECRGB.
;ulStart (ULONG) - input:Starting index, that is, first palette entry to change.
;cclr (ULONG) - input:Count of palette entries to change.
;pclr (PULONG) - input:Pointer to table of new RGB2 palette entries.
;pInstance (PVOID) - input:Pointer to instance data.
;lFunction (ULONG) - input:High-order WORD=flags; low-order WORD=NGreDeviceSetPaletteEntries.

== Returns ==
;rc (BOOL) - returns:Return codes.
:This function returns BOOLEAN (fSuccess).
:*TRUE Successful, if entries set without error
:*FALSE Error
:Possible Errors Detected: When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:
:*PMERR_INV_IN_AREA
:*PMERR_INV_IN_PATH
:*PMERR_INV_COLOR_INDEX
