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.

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):

Here's an example code:

#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);

}

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

[Switching to process 1475]

Any thoughts?
