vmmap & pmap is essentially the same but vmmap is for mac

Using the Smallest C Program to Better Understand Your System (with pmap, vmmap, and strace).

#include <stdio.h>

int main()
{
	printf("hello world\\n");
	while (1) {}
}

• above code will generate alot of memory allocation when logged with strace
• strace is the system call tracer

_start(){while(1){}}

compiled with
cc -nostdlib test.c

• above would be a much smaller code
• doing strace and pmap on the above code will significant reduce the syscall and memory mapped by the program compared to hello world program
