Hello all expert C programmer and hacker, i truly a noob in this field.
I have a program that print stack pointer but i don't really know its underlying concept.
I hope you all can explain it to me. When i try to compiled this program , unresolve external symbol means i didn't finish up the function definition
Below is my program :
Quote:
// A little program to print stack pointer
#include<stdio.h>
int main()
{
printf("0x%x\n", get_sp());
return 0;
}
unsigned long get_sp()
{
__asm__("movl %esp,%eax");
}
