# XSetArcMode(3x)

GC convenience routines

## NAME

XSetArcMode, XSetSubwindowMode, XSetGraphicsExposure - GC convenience routines

## SYNTAX

int XSetArcMode(Display \**display*, GC *gc*, int *arc\_mode*);

int XSetSubwindowMode(Display \**display*, GC *gc*, int *subwindow\_mode*);

int XSetGraphicsExposures(Display \**display*, GC *gc*, Bool *graphics\_exposures*);

## ARGUMENTS

- *arc\_mode*

  Specifies the arc mode. You can pass *ArcChord* or *ArcPieSlice*.

- *display*

  Specifies the connection to the X server.

- *gc*

  Specifies the GC.

- *graphics\_exposures*

  Specifies a Boolean value that indicates whether you want *GraphicsExpose* and *NoExpose* events to be reported when calling *XCopyArea* and *XCopyPlane* with this GC.

- *subwindow\_mode*

  Specifies the subwindow mode. You can pass *ClipByChildren* or *IncludeInferiors*.

## DESCRIPTION

The *XSetArcMode* function sets the arc mode in the specified GC.

*XSetArcMode* can generate *BadAlloc*, *BadGC*, and *BadValue* errors.

The *XSetSubwindowMode* function sets the subwindow mode in the specified GC.

*XSetSubwindowMode* can generate *BadAlloc*, *BadGC*, and *BadValue* errors.

The *XSetGraphicsExposures* function sets the graphics-exposures flag in the specified GC.

*XSetGraphicsExposures* can generate *BadAlloc*, *BadGC*, and *BadValue* errors.

## DIAGNOSTICS

- *BadAlloc*

  The server failed to allocate the requested resource or server memory.

- *BadGC*

  A value for a GContext argument does not name a defined GContext.

- *BadValue*

  Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted.  Any argument defined as a set of alternatives can generate this error.
