I am surprised by GCC (this is ver. 4.2.4, Ubuntu 32 bit Intel) when a function declares a float parameter and it's prototype is missing, the parameters are messed up.
Please see my code below:
The output:
As you see, the set_P function somehow messed up parameters.
***Note: the code does work on SCO with stock compiler on similar h/w.
If I add the function prototype to x1.c
then everything works correctly, no surprises.
My understanding is that compiler allocates longs for longs/integers/shorts and doubles for float/double when passing parametrs by value. Then if receiver function expects a float, it will get first 32 bit, which is OK on Intel. Apparently my understanding is not correct.
The code in many places lacks function prototypes, I wander if I can somehow influence compiler to pass float/double parameters and not mess up. Any ideas?
I need to pass a parameter to a function in a script. My parameter is a string. When I display the parameter within my function, I only get the first word from string I pass in.
How can I make the function receive the whole string (and not terminate at the first space it encounters)?.

Hi All,
When passing parameters to a sheel script, the parameters are referenced by their positions such as $1 for first parameter, $2 for second parameter. these positional values can only have values ranging from $0-$9 (0,1,2,3...9).

Viewport(3I) InterViews Reference Manual Viewport(3I)NAME
Viewport - scrollable view
SYNOPSIS
#include <InterViews/viewport.h>
DESCRIPTION
Viewport is a subclass of MonoScene that allocates its component exactly as much space as it wants (determined from its shape). This space
will be clipped to the viewport's size and the viewport maintains a perspective to adjust the portion of the component that is actually
displayed. If the component is smaller than the viewport's canvas, then the viewport background will be filled with a light gray pattern.
PUBLIC OPERATIONS
Viewport(Interactor* = nil, Alignment = Center)
Construct a new viewport. If the interactor is not nil, it is inserted as the viewport's component. The second parameter deter-
mines where the component is placed relative to the viewport.
Insert(Interactor*)
Set the component interactor.
void Change(Interactor*)
A viewport does not propagate changes. Thus, if the component's shape changes the viewport simply resizes the component according
to the new shape.
void Remove(Interactor*)
Take out the component interactor.
virtual void Adjust(Perspective&)
Change the viewport's perspective to the given one. This operation will cause the desired area of the component to be drawn.
void AdjustTo(float px, float py, float zx, float zy)
void AdjustBy(float dpx, float dpy, float dzx, float dzy)
void ScrollTo(float px, float py)
void ScrollXTo(float px)
void ScrollYTo(float py)
void ScrollBy(float dpx, float dpy)
void ScrollXBy(float dpx)
void ScrollYBy(float dpy)
void ZoomTo(float zx, float zy)
void ZoomXTo(float zx)
void ZoomYTo(float zy)
void ZoomBy(float dzx, float dzy)
void ZoomXBy(float dzx)
void ZoomYBy(float dzy)
Short-hand operations for explicit manipulation of the viewport's perspective.
float XPos()
float YPos()
float XMag()
float YMag()
Short-hand for retrieving information about the current perspective.
