什么是Linux中的Getch()&getche()？我無法在Linux中找到conio.h的等效頭文件。有什么可供選擇的嗎？getch() & getche()Linux中的函數(shù)？我想做一個開關案例基礎菜單，用戶將提供他的選擇，只要按一個鍵&進程應該向前移動。我不想讓用戶按回車后，按下他的選擇。

char getch(){
/*#include <unistd.h> //_getch*/
/*#include <termios.h> //_getch*/
char buf=0;
struct termios old={0};
fflush(stdout);
if(tcgetattr(0, &old)<0)
perror("tcsetattr()");
old.c_lflag&=~ICANON;
old.c_lflag&=~ECHO;
old.c_cc[VMIN]=1;
old.c_cc[VTIME]=0;
if(tcsetattr(0, TCSANOW, &old)<0)
perror("tcsetattr ICANON");
if(read(0,&buf,1)<0)
perror("read()");
old.c_lflag|=ICANON;
old.c_lflag|=ECHO;
if(tcsetattr(0, TCSADRAIN, &old)<0)
perror ("tcsetattr ~ICANON");
printf("%c\n",buf);
return buf;
}remove the last printf if you dont want the char to be displayed
