如何在命令行应用程序中使用仪器并显示控制台

但是，从仪器中启动应用程序时，我找不到显示控制台的方法。我也无法附加到正在运行的命令行进程(它会出现错误)：

以下是一个示例代码：

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

static sigjmp_buf jmpbuf;

void handler(int sig) {
    char c[BUFSIZ];

    printf ("Got signal %dn",sig);
    printf ("Deseja sair? (s/n) ");

    fgets(c,sizeof(c),stdin);

    if(c[0] == 's') {
        exit(0);
    } else {
        siglongjmp(jmpbuf,1);
    }
}

int main(void) {
    char buf[BUFSIZ];

    signal(SIGINT,handler);

    sigsetjmp(jmpbuf,1);

    while(1) {
        printf(">>>");
        fgets(buf,sizeof(buf),stdin);
        printf ("Introduziu: %sn",buf);
    }

    return(0);
}

以下是启动仪器后发现的错误，并尝试附加到xcode中运行的进程：

有什么想法吗？
