Question

我想禁用键盘快捷键，例如Ctrl + C，Ctrl + V，等等...

我能为此做些什么？

system(/* How to do? */);

在C ++（或C中，您告诉我们C ++但您标记了C）CTRL + C快捷方式实际上是SIGINT信号。 SIGINT是一个描述键盘中断的信号（所有信号列表都可以在signal(7)找到。

您可以使用siganl(2)函数（在C / C ++中正常工作）更改默认信号的压缩（如分段错误，浮点异常等...），就像它一样：

#include <signal.h>
#include <stdio.h>

void    sigint_handler(int signum)
{
    (void) signum;
    /* Let this function empty to totally "disable" your signal interpretation */
    /* or just let a printf to see when you pass into */
    printf("Received SIGINT\r\n");
}

void    sigsegv_handler(int signum)
{
    (void) signum;
    /* Let this function empty to totally "disable" your signal interpretation */
    /* or just let a printf to see when you pass into */
    printf("Received SIGINT\r\n");
}

int     main(void)
{
        signal(SIGINT, sigint_handler);
        signal(SIGSEGV, sigsegv_handler);
        /* From now, each time your program will receive a SIGINT */
        /* it will pass into the sigint_handler function and do a printf */
        /* and same for Segfault signal */
        while (1);
        return (0);
}

不确定它是不是你想要的，但我希望我能帮到你。
