方法一：

#include 
     
      #include 
      
       int main (void){    struct winsize w;    ioctl(0, TIOCGWINSZ, &w);    printf ("lines %d\n", w.ws_row);    printf ("columns %d\n", w.ws_col);    return 0;}
      
     

 

方法二：

#include 
     
      #include 
      
       #include 
       
        #include 
        
         static char termbuf[2048];int main(void){    char *termtype = getenv("TERM");    if (tgetent(termbuf, termtype) < 0) {        error(EXIT_FAILURE, 0, "Could not access the termcap data base.\n");    }    int lines = tgetnum("li");    int columns = tgetnum("co");    printf("lines = %d; columns = %d.\n", lines, columns);    return 0;}
        
       
      
     

注意：Needs to be compiled with -ltermcap . There is a lot of other useful information you can get using termcap. Check the termcap manual using info termcap for more details.
