Ncurses Library realizes electronic clock

1. Create GRAPHICS.C

2. Edit GRAPHICS.C, compile:

Gcc-o graphic graphic.c-l/usr/lib/i386-linux-gnu/-lncurses

The source code of 3.GRAPHICS.C is as follows:

[email protected]:/mnt/shared/appbox/graphic# cat graphic.c#include <curses.h> #include <stdio.h># Include <stdlib.h> #include <unistd.h> #include <string.h> #include <ncurses.h> #include < unistd.h> #include <time.h> #include <string.h> #include <stdlib.h> #include <pthread.h>#    Include <errno.h>int main () {int x, y;    Gets the number of rows and columns of the current standard window time_t t;    pthread_t thread;    WINDOW *win;          INITSCR ();        Initialize standard window, must drop Curs_set (0);           Hide cursor dynamic noecho ();       Input no echo getmaxyx (stdscr,y,x);  Gets the number of rows and columns of the standard window Win=newwin (5,40,Y/2-5/2,X/2-40/2);          Create a window in the center of the standard window refresh ();      Refresh the standard window, or you will not be able to display the newly created window Wrefresh (win);      Refresh the newly created window Getmaxyx (win,y,x);  Gets the number of rows and columns of the new window while (1)//infinite loop {t=time (NULL);   Get all the seconds from a certain time to now MVWPRINTW (WIN,Y/2,X/10, "["); Enter the date and time at the center of the new window using the CTime function to convert MVWPRINTW (win,y/2,x/2-(strlen (CTime (&t)) +1)/2, "%s ", CTime (&t));   Enter the date and time at the center of the newly created window using the CTime function to convert mvwprintw (WIN,Y/2,4*X/5, "]");           Enter the date and time in the center of the newly created window using the CTime function to convert Wrefresh (win);                     Refresh the window, or you will not be able to display the date and time sleep (1);        Suspend one second} endwin (); return 0;}  [email protected]:/mnt/shared/appbox/graphic#
