如何在命令行应用程序中使用乐器并显示控制台 [英] How use Instruments and display the console in Command Lines applications

问题描述

我正在OSX上使用Xcode开发命令行C应用程序.我还想使用Instruments来分析和查找内存泄漏.

I'm using Xcode on OSX to develop command line C applications. I would also like to use Instruments to profile and find memory leaks.

但是，从Instruments内部启动应用程序时，我找不到找到控制台的方法.我也无法附加到正在运行的命令行进程(它退出并出现错误):

However, I couldn't find a way to display the console when launching the application from within Instruments. I'm also unable to attach to a running command line process (it exits with an error):

这是示例代码:

#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 %d\n", 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: %s\n", buf);
    }

    return(0);
}

这是在启动Instruments并尝试附加到xcode中正在运行的进程后出现的错误:

Here's the error I got after launching Instruments, and trying to attach to the running process in xcode:

[Switching to process 1475]

有什么想法吗?
