Hello,

I'm a Summer Student and I've a problem with root.
I would like to read a data file like this:

25 ext probe 1 21.93 1052989373314
26 ext probe 1 19.95 1052989373362
27 ext probe 1 20.25 1052989373418
28 ext probe 1 20.40 1052989373465
29 ext probe 1 20.36 1052989373517
30 ext probe 1 19.99 1052989373620
31 ext probe 1 21.17 1052989373683

In order to do this, I have written a script:

{
  gROOT->Reset();

  int id;
  char name1[10];
  char name2[10];
  int type;
  float measure;
  int timestamp;
  char temp[200];
  FILE *apre;

  apre = fopen("extprobe.dat","r");

  while(fgets(temp, sizeof(temp), apre) !=NULL) {

    sscanf(temp, "%d %s %s %d %g %d",
    &id, &name1,&name2,  &type, &measure, &timestamp);
    printf("%d %s %s %d %g %d\n",
    id, name1,name2, type, measure, timestamp);

  }

    fclose(apre);
}


Alas, it doesn't work, because it can't manage to read the last number
of each line (it's too long).
Could you give any hint?

Thank you very much.
