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; }
