Simple use of Leaks Instrument on a console application

I would like a simple example on how to use the Leaks tool.

see:

#include <iostream>

int main (int argc, char * const argv[]) {
  char *buf = new char[100];

  sprintf(buf, "Hello, World!\n");
  // insert code here...
  std::cout << buf;
  return 0;
}

the code above(simple example) should leak the pointer allocated on开发者_如何学运维 *buf, right?

with valgrind I would find this very easy after a run

but I just can't find how to do this on the Leaks program

I tried to put sleep(60) but it is still not friendly to me...

thanks,

Jonathan

I've found that Leaks doesn't work all that well with command line applications that exit quickly. I would suggest adding a sleep() like you've done, but add one before the main program logic, and again at the end, so that Leaks is likely to sample the leaked state.

int main() {
  sleep(20); // 20s may be enough
  {
     // do leaky operations, then local variables will go out of scope
  }
  sleep(20);
}
