Examining C/C++ Heap memory statistics in gdb

Question

I\'m trying to investigate the state of the C/C++ heap from within gdb on Linux amd64, is there a nice way to do this?

One approach I\'ve tried is to \"call mallinfo

Answer 1

If you can change the code:

#include 
#include 

void dumpMallinfo(void) {
  struct mallinfo m = mallinfo();
  printf("uordblks = %d\nfordblks = %d\n", m.uordblks, m.fordblks);
}

In GDB, you can call dumpMallinfo().
