NAME

XSetState, XSetFunction, XSetPlanemask, XSetForeground, XSetBackground − GC convenience routines

SYNTAX

XSetState(display, gc, foreground, background, function, plane_mask)
      Display ∗display;
      GC gc;
      unsigned long foreground, background;
      int function;
      unsigned long plane_mask;

XSetFunction(display, gc, function)
      Display ∗display;
      GC gc;
      int function;

XSetPlaneMask(display, gc, plane_mask)
      Display ∗display;
      GC gc;
      unsigned long plane_mask;

XSetForeground(display, gc, foreground)
      Display ∗display;
      GC gc;
      unsigned long foreground;

XSetBackground(display, gc, background)
      Display ∗display;
      GC gc;
      unsigned long background;

ARGUMENTS

backgroundSpecifies the background you want to set for the specified GC.

displaySpecifies the connection to the X server.

foregroundSpecifies the foreground you want to set for the specified GC.

functionSpecifies the function you want to set for the specified GC.

gcSpecifies the GC.

plane_maskSpecifies the plane mask.

DESCRIPTION

The XSetState function sets the foreground, background, plane mask, and function components for the specified GC.

XSetState can generate BadAlloc, BadGC, and BadValue errors.

XSetFunction sets a specified value in the specified GC.

XSetFunction can generate BadAlloc, BadGC, and BadValue errors.

The XSetPlaneMask function sets the plane mask in the specified GC.

XSetPlaneMask can generate BadAlloc and BadGC errors.

The XSetForeground function sets the foreground in the specified GC.

XSetForeground can generate BadAlloc and BadGC errors.

The XSetBackground function sets the background in the specified GC.

XSetBackground can generate BadAlloc and BadGC 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.
