在Linux中相当于getch()和getche()?

我在Linux中找不到conio.h的等效头文件。

Linux中有getch()getche()功能选项吗?

我想创建一个切换案例基​​础菜单,用户只需按一个键就可以给出选项,并且过程应该向前移动。我不想让用户按其选择后按ENTER。

#include <termios.h>

#include <stdio.h>

static struct termios old, current;

/* Initialize new terminal i/o settings */

void initTermios(int echo)

{

tcgetattr(0, &old); /* grab old terminal i/o settings */

current = old; /* make new settings same as old settings */

current.c_lflag &= ~ICANON; /* disable buffered i/o */

if (echo) {

current.c_lflag |= ECHO; /* set echo mode */

} else {

current.c_lflag &= ~ECHO; /* set no echo mode */

}

tcsetattr(0, TCSANOW, &current); /* use these new terminal i/o settings now */

}

/* Restore old terminal i/o settings */

void resetTermios(void)

{

tcsetattr(0, TCSANOW, &old);

}

/* Read 1 character - echo defines echo mode */

char getch_(int echo)

{

char ch;

initTermios(echo);

ch = getchar();

resetTermios();

return ch;

}

/* Read 1 character without echo */

char getch(void)

{

return getch_(0);

}

/* Read 1 character with echo */

char getche(void)

{

return getch_(1);

}

/* Let's test it out */

int main(void) {

char c;

printf("(getche example) please type a letter: ");

c = getche();

printf("\nYou typed: %c\n", c);

printf("(getch example) please type a letter...");

c = getch();

printf("\nYou typed: %c\n", c);

return 0;

}

输出:

(getche example) please type a letter: g

You typed: g

(getch example) please type a letter...

You typed: g
