XSetFunction(display, gc, function)
      Display *display;
      GC gc;

XSetFunction() can generate BadAlloc , BadGC , and BadValue errors.


BadAlloc The server failed to allocate the requested source 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.
