I can't find anything in it that I am looking for, having issues reading the documentation

KuraKai · Mar 12th, 2008, 6:03 PM

Ok, scratch that post I was able to get through the documentation just took a bit. I not have decent lines going. But now I have to figure out how to use putwin() and getwin(). This is going to be a stupid question but what is a FILE *? How do I create one and such, I know it's a pointer to a file but is it the stream or something or just the location of the file?

FILE is whats known as an opaque data type. Its actually a struct, but we don't really care whats in it. How files work below the C library level is OS dependent.

Using C, you can create a file using the fopen function.

Ok, no that that works I am having issues tying to use color_set(), what the hell is a void *? I start the color and try to change it to COLOR_BLUE and it does not change the color at all, anyone know how to get it to work?

void * is a pointer to anything. It needs to be casted to a datatype to be of any use. Notice that malloc() return void *, this is because all malloc does is allocate bytes, how those bytes are interpreted depends on the data type.

Well I passed it anything and it still has yet to make anything blue.

 C++ Syntax (Toggle Plain Text) 
#include "curses.h"
 
void main()
{
	WINDOW * win = initscr();
	start_color();
	resize_term(25, 80);
	curs_set(2);
	noecho();
 
	color_set(COLOR_BLUE, win);
	wborder(win, 0, 0, 0, 0, 0, 0, 0, 0);
}
#include "curses.h"

void main()
{
	WINDOW * win = initscr();
	start_color();
	resize_term(25, 80);
	curs_set(2);
	noecho();

	color_set(COLOR_BLUE, win);
	wborder(win, 0, 0, 0, 0, 0, 0, 0, 0);
}

Also here is the code for color_set...

 C++ Syntax (Toggle Plain Text) 
int wcolor_set(WINDOW *win, short color_pair, void *opts)
{
	PDC_LOG(("wcolor_set() - called\n"));
 
	if (!win)
		return ERR;
 
	win->_attrs = (win->_attrs & ~A_COLOR) | COLOR_PAIR(color_pair);
 
	return OK;
}
 
int color_set(short color_pair, void *opts)
{
	PDC_LOG(("color_set() - called\n"));
 
	return wcolor_set(stdscr, color_pair, opts);
}
int wcolor_set(WINDOW *win, short color_pair, void *opts)
{
	PDC_LOG(("wcolor_set() - called\n"));

	if (!win)
		return ERR;

	win->_attrs = (win->_attrs & ~A_COLOR) | COLOR_PAIR(color_pair);

	return OK;
}

int color_set(short color_pair, void *opts)
{
	PDC_LOG(("color_set() - called\n"));

	return wcolor_set(stdscr, color_pair, opts);
}

According to the color_set manual page,

Quote:

The routine color_set sets the current color of the given window to the foreground/background combination described by the color_pair_number. The parameter opts is reserved for future use, applications must supply a null pointer.

KuraKal: After reading your posts in this thread my impression is that you haven't the slightest notion of what the hell you are doing. You have absolutly zero training in either C or C++ so what the hell are you doing trying to write this program? Stop right now and buy an Intruduction to C language book at your local book store or online at amazon.com. Then begin reading and studying form page 1. You are just wasting your and everyone's time posting these questions that any 1st semester student should have learned. This is not the place to teach you c language -- that's what books are written for and the thousands of online tutorials attempt to do.
