mixing c and assembly. On the terminal nothing printed

[vardan9]

I wrote here is a simple code:

printf.asm
 
 [EXTERN main]
 section .text
 global _start     
 _start:
       call main
       add esp, 8
       mov eax, 1
       xor ebx, ebx
       int 80h

and main.c

#include <stdio.h>
 
 int main()
 {
     char* str = "print from C :\\)";
     printf("%s", str);
 }

I compile code like this:

nasm -g -f elf printf.asm -o printf.o
 
gcc -c -o main.o main.c
 
ld -o printf printf.o main.o -lc -I/lib/ld-linux.so.2

And run:

./printf

On the terminal nothing printed. Why ?

How to solve this problem ?

What does "int 80h" do ( line 11 of printf.asm)?
If printf output is spooled, then your program could hit that "int 80h" before any characters are output. If that int stops the program then you might not see any output.
