Linux中的getch()和getche()相当于什么?
作者:互联网
我无法在Linux中找到conio.h的等效头文件.
getch()&是否有任何选项? Linux中的getche()函数?
我想制作一个开关盒基本菜单,用户只需按一个键即可给出他的选项.过程应该向前推进.按下他的选择后,我不想让用户按ENTER键.
解决方法:
#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, ¤t); /* 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
