GreUnrealizeColorTable

GreUnrealizeColorTable reverses GreRealizeColorTable by causing the default physical color table for the device to be reinstated.

This function must be supported by the presentation driver. GreUnrealizeColorTable is called by GpiUnRealizeColorTable in response to the request of an application to restore the application's logical color table prior to the last call to GpiRealizeColorTable. This function can be handled by bit-map simulation.


 * Simulation support: None. This function is mandatory for all drivers.

Syntax
GreUnrealizeColorTable(hdc, pInstance, lFunction)

Parameters

 * hdc (HDC) - input : Device context handle.
 * pInstance (PVOID) - input : Pointer to instance data.
 * lFunction (ULONG) - input : High-order WORD=flags; low-order WORD=NGreUnrealizeColorTable.

Returns
On completion, the handling routine must return a BOOLEAN value to indicate success or an 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: Refer to the "Error Explanations" section in the Presentation Manager Programming Reference for further explanation.
 * rc (BOOL) - returns : Return codes.
 * TRUE Successful
 * FALSE Error
 * PMERR_COL_TABLE_NOT_REALIZED
 * PMERR_DEV_FUNC_NOT_INSTALLED
 * PMERR_INV_HDC
 * PMERR_INV_IN_AREA
 * PMERR_INV_IN_PATH

Remarks
The logical color table is unaffected by this function.


 * Note: GreUnrealizeColorTable is provided for the support of older applications and is of less importance for new applications.
