函数名: wherex
功  能: 返回窗口内水平光标位置
用  法: int wherex(void);
程序例:

#include <conio.h>

int main(void)
{
   clrscr();
   gotoxy(10,10);
   cprintf("Current location is X: %d  Y: %d\r\n", wherex(), wherey());
   getch();

   return 0;
}
 
 
 

函数名: wherey
功  能: 返回窗口内垂直光标位置
用  法: int wherey(void);
程序例:

#include <conio.h>

int main(void)
{
   clrscr();
   gotoxy(10,10);
   cprintf("Current location is X: %d  Y: %d\r\n", wherex(), wherey());
   getch();

   return 0;
}
 
 
 

函数名: window
功  能: 定义活动文本模式窗口
用  法: void window(int left, int top, int right, int bottom);
程序例:

#include <conio.h>

int main(void)
{

   window(10,10,40,11);
   textcolor(BLACK);
   textbackground(WHITE);
   cprintf("This is a test\r\n");

   return 0;
}
 
 
 

函数名: write
功  能: 写到一文件中
用  法: int write(int handel, void *buf, int nbyte);
程序例:

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <sys\stat.h>
#include <io.h>
#include <string.h>

int main(void)
{
   int handle;
   char string[40];
   int length, res;

   /*
    Create a file named "TEST.$$$" in the current directory and write
    a string to it.  If "TEST.$$$" already exists, it will be overwritten.
   */

   if ((handle = open("TEST.$$$", O_WRONLY | O_CREAT | O_TRUNC,
                         S_IREAD | S_IWRITE)) == -1)
   {
      printf("Error opening file.\n");
      exit(1);
   }

   strcpy(string, "Hello, world!\n");
   length = strlen(string);

   if ((res = write(handle, string, length)) != length)
   {
      printf("Error writing to the file.\n");
      exit(1);
   }
   printf("Wrote %d bytes to the file.\n", res);

   close(handle);
   return 0;
}
