GreCloseFigure

GreCloseFigure closes a figure within a path definition by drawing a line from the current (X,Y) position to the start point of the figure. Upon completion, the current position is the start point of the figure. "Open figures" can be generated by starting a new figure (with a Move function) or by ending the path without first closing the figure. GreCloseFigure is valid outside of a path definition. When this occurs, this function has no effect and the handling routine ignores it. For more information, see GpiCloseFigure in the Presentation Manager Programming Reference.

This function can be hooked by the presentation driver.

Simulation support

This function is simulated by a handling routine in the graphics engine.

Syntax

GreCloseFigure(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=NGreCloseFigure.

Return Code

rc (BOOL) - returns

This function returns BOOLEAN (fSuccess).

• TRUE Successful
• 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_BASE_ERROR
• PMERR_COORDINATE_OVERFLOW
• PMERR_DEV_FUNC_NOT_INSTALLED
• PMERR_HDC_BUSY
• PMERR_INV_COORD_SPACE
• PMERR_INV_HDC
• PMERR_INV_LENGTH_OR_COUNT
• PMERR_NOT_IN_PATH
• PMERR_PATH_LIMIT_EXCEEDED
