--- Comment #4 from Elder <eldereng at hotmail dot com> 2013-01-16 16:49:59 UTC ---
Correct Josh, but if I build my code with debug it should work right?
In my case, this did not work. Look:

My code is (Command for compile is: gcc -g -o Application Application.c):
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
int TimeForSleep();
int TimeForSleep(){
  double nr=3.0;
  return 1000000 * nr;
}
int main(int argc,char *argv[]){
  while(1){
    printf("test \n");
    usleep(TimeForSleep()); 
  }
  return 0;
}


My script of systemtap:
probe process("/home/elder/Application").function("TimeForSleep").call 
{
 printf("found\n"); 
}
probe begin {
 printf("INI\n"); 
}
probe end {
 printf("FIM \n"); 
}



Return of systemtap:
