Trying to use ptrace under FBSD

[Gema niskazhu]

Hi all!

First of all sorry for my bad english.

I am using Free BSD CURRENT x86_64.

I am trying to  use ptrace under free bsd

simply to test that it works

Here is my code:

#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <sys/ptrace.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <unistd.h>
#include <errno.h>


main()
{
  int pid;
  int wait_val;
  long long counter = 1;

  switch(pid = fork() )
  {
  case 0:


  ptrace(PT_TRACE_ME, 0, 0);



  execl("/bin/ls","ls",0);
  break;

  default:


  wait(&wait_val);

 while(WIFSTOPED(wait_val))
  {
  if (ptrace(PT_STEP, pid, *(caddr_t)1)) break;

  wait(&wait_val);

  counter++;
  }


  }

  printf("==%lld\n", counter);


}

But on compilation i get smth like

/usr/include/sys/ptrace.h:90: error: expected specifier-qualifier-list
before 'lwpid_t'
/usr/include/sys/ptrace.h:158: error: expected declaration specifiers or
'...' before 'caddr_t'

I've googled a lot but cant understand whats wrong...

Any suggestions?

Thanks in advance
