conio.h不是C标准库中的头文件。
包含的函数: cgets(char *); cprintf(const char *, ...); cputs(const char *); cscanf(const char *, ...); inp(unsigned short); inpw(unsigned short); getch(void); getche(void); kbhit(void); outp(unsigned short, int); outpw(unsigned short, unsigned short); putch(int); ungetch(int); void _Cdecl clreol (void); void _Cdecl clrscr (void); void _Cdecl delline (void); int _Cdecl gettext (int left, int top, int right, int bottom, void *destin); void _Cdecl gettextinfo (struct text_info *r); void _Cdecl gotoxy (int x, int y); void _Cdecl highvideo (void); void _Cdecl insline (void); void _Cdecl lowvideo (void); int _Cdecl movetext (int left, int top, int right, int bottom, int destleft, int desttop); void _Cdecl normvideo (void); int _Cdecl puttext (int left, int top, int right, int bottom, void *source); void _Cdecl textattr (int newattr); void _Cdecl textbackground (int newcolor); void _Cdecl textcolor (int newcolor); void _Cdecl textmode (int newmode); int _Cdecl wherex (void); int _Cdecl wherey (void); void _Cdecl window (int left, int top, int right, int bottom); char *_Cdecl cgets (char *str); int _Cdecl cprintf (const char *format, ...); int _Cdecl cputs (const char *str); int _Cdecl cscanf (const char *format, ...); int _Cdecl getch (void); int _Cdecl getche (void); char *_Cdecl getpass (const char *prompt); int _Cdecl kbhit (void); int _Cdecl putch (int c); int _Cdecl ungetch (int ch); 编辑本段 用法 conio 库不仅适用于 Window 平台,在 Linux 下也可使用.网上已经有兼容包,下载后打开就可使用;而至于Mac则完全跟Window没有区别,直接可以使用.
demo:
#include "StdAfx.h"
int main(int argc,char* argv[]){
/*
函数名:kbhit()(VC++6.0下为_kbhit())
功 能及返回值: 检查当前是否有键盘输入,若有则返回一个非0值,否则返回0
用 法:int kbhit(void);
包含头文件: include <conio.h>
*/
/*
cprintf("Press any key to continue.\n");
int i=0;
while( !(i=kbhit()) ){
cprintf("\n no key pressed.");
}
printf("\nkbhit() return: %d.",i);
getch();
*/
//system("pause");
//press one key to exit.
printf("press any to continue...\n");
char ch= getch();
printf("you pressed %c.\n done\n",ch);
/* //get environment variable
char * chPath = getenv("pathext");
printf("%s\n",chPath);
int i= getchar();
printf("%c",i);
*/
return 0;
