How to detect an empty file?

Dear all,

I thought the code
-----------------------------
pt_fichier_probleme = fopen(nom_fichier, "w");

if(pt_fichier_probleme == NULL){
message_warning_s
("Erreur l'ouverture du fichier\n%s\n", (gchar *)nom_fichier);
return;}
else {
rewind(pt_fichier_probleme); /* Be sure we're at beginning */
if(feof(pt_fichier_probleme) == 0){
/* We are not at end of buffer ... It means the
file already has some content!! */
if( AskConfirmation(user_data) == 0){
/* L'utilisateur ne veut pas qu'on ecrive sur le fichier !!*/
fclose(pt_fichier_probleme);
return;};
};};
-----------------------------

was an excellent way of
-- opening the file nom_fichier for writing,
-- detecting a mistake if it was not possible,
-- if the file was not empty, the askign the
user whether it still wants to overwrite it.
(that's AskConfirmation : a window with the question and so on)
As it turns out, confirmation is always asked :-(

Help?
Best !
Amities,
Olivier
