Thread: after exit(1) from curses program, terminal has no text

Hi cprogramming,
I have a program where
1. the user can choose to display an ascii pic from three options
2. the pic displays in a curses window for, say 10 seconds (10 is a cmd line arg)
3.the menu of the 3 pics returns
if the user hits ctrl-c, the program should display a message, wait 3 seconds, then exit (using exit(1)).

I have a trial program that uses signal(SIGINT, func), that exits fine.
BUT, when i try a similar func in the middle of a curses program, the signal function exits, BUT then the terminal screen will not show any characters typed in, and the prompt will be LINE-1 COL+1

I'm new to signals and curses, so I don't know where the problem lies

here is my test program for signal(SIGINT,func), it works fine

Code:

#include<stdio.h>
#include<signal.h>

void handler(void)
{
	printf("timeout!\n");
	signal(SIGALRM, handler); //reset the action
	sleep(5); 
	exit(1);
}

int main(void)
{
	signal(SIGINT,handler); 

	while(1)
	{
		printf("PRESS <RETURN>\n");
		getchar();
	}
}

here is my main and func from the prog that causes terminal to mess up

Code:

#include<stdio.h>
#include<stdlib.h>
#include<signal.h>
#include<curses.h>

void func_handler(void)
{
	printf("\nquitting in 3 seconds\n");
	refresh();
	signal(SIGALRM, func_handler); //reset teh action
	sleep(3); 
	
	exit(1);
}

Code:

#include<stdio.h>
#include<curses.h>
#include "lib.h"
#include <signal.h>
#include<stdlib.h>

int main(int argc, char *argv[])
{
	int delay;
	
	signal(SIGINT,func_handler); //set the action
	
	
	
	
	sscanf(argv[1],"%d", &delay); //get argv[1] and convert from string to int
											//using sscanf

	char choice;
	initscr();
	choice =' ';
	do 
	{
		move(13,0);
		addstr("\nPress 1 for Sam,2 for Norm,3 for Rad 4 to quit: ");
		refresh();
		
		choice = getchar();
		if(choice =='1')
		{
			sd();
			sleep(delay);	
			
		}
		else if(choice =='2')
		{
			nd();
			sleep(delay);
		}
		else if(choice =='3')
		{
			rei();
			sleep(delay);
		}
	}while(choice != '4');
	
	endwin();
}

Solved

Code:

#include<stdio.h>
#include<stdlib.h>
#include<signal.h>
#include<curses.h>

void func_handler(void)
{
	printf("\nquitting in 3 seconds\n");
	refresh();
	signal(SIGALRM, func_handler); //reset teh action
	sleep(3); 
	endwin(); //needed this line
	exit(1);
}
