First, i know java well and i have used C++ on occasion so i thought i would be able to deal with a class where they program in C. unfortunately i have hit some speed bumps that i am having problems.
Here is my problem:
I have a structure cache_t in the sample program we are supposed to use. In one of my functions i am supposed to use a pointer to an instance of this cache_t struct to perform some operations and return a value.
How do i get the value of nsets? i have tried &cp.nsets but that just gives me an error:
error: request for member 'nsets' in something not a structure or union

ah, nevermind. As i guessed it was my inexperience with C causing problems. I was looking for cp->nsets.

bumps
XScreenSaver(1) General Commands Manual XScreenSaver(1)NAME
bumps - move distorting spotlight around desktop
SYNOPSIS
bumps [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay
usecs] [-radius pixels]
DESCRIPTION
The bumps program takes an image and exposes small, distorted sections of it as if through an odd wandering spotlight beam.
The image that it manipulates will be grabbed from the portion of the screen underlying the window, or from the system's video input, or
from a random file on disk, as indicated by the grabDesktopImages, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver
file; see xscreensaver-demo(1) for more details.
OPTIONS
bumps accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
-delay microseconds
Slow it down.
-radius pixels
Radius of the spotlight in pixels.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
