### GreFillPath - Parameters

hdc (HDC) - input Device context handle.

idPath (LONG) - input Path ID. It must be 1.

flOptions (ULONG) - input Option flags.

These flags determine how the path is to be filled:

FPATH_ALTERNATE Fill is performed by using the odd/even (alternate) rule.
FPATH_WINDING Fill is performed by using the winding rule.
FPATH_EXCL Fill exclusive of bottom and right border in device coordinate.

pInstance (PVOID) - input Pointer to instance data.

lFunction (ULONG) - input High-order WORD=flags; low-order WORD= NGreFillPath.

rc (LONG) - returns Return codes.

This function returns an integer (cHits) indicating, where appropriate, whether correlation hits were detected:

GPI_OK Successful
GPI_HITS Successful with correlate hit (returned by display drivers when the correlate flag is ON, and a hit is detected)
GPI_ERROR 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_BASE_ERROR
PMERR_BITMAP_NOT_SELECTED
PMERR_COORDINATE_OVERFLOW
PMERR_DEV_FUNC_NOT_INSTALLED
PMERR_HDC_BUSY
PMERR_HRGN_BUSY
PMERR_INSUFFICIENT_MEMORY
PMERR_INV_COLOR_DATA
PMERR_INV_COLOR_INDEX
PMERR_INV_COORD_SPACE
PMERR_INV_COORDINATE
PMERR_INV_FILL_PATH_OPTIONS
PMERR_INV_HDC
PMERR_INV_HRGN
PMERR_INV_IN_AREA
PMERR_INV_IN_PATH
PMERR_INV_LENGTH_OR_COUNT
PMERR_INV_PATH_ID
PMERR_INV_PICK_APERTURE_POSN
PMERR_INV_RECT
PMERR_INV_REGION_CONTROL
PMERR_PATH_LIMIT_EXCEEDED
PMERR_PATH_UNKNOWN
PMERR_REGION_IS_CLIP_REGION
