[fopen] Diff�rence entre a et a+

Bonjour,

J'aimerais savoir la diff�rence entre "a" et "a+" dans la fonction fopen...

Exemple :
[Code]
fichierLiaison = fopen("C:\\Temp\\salut.txt", " at ou a+t") ;

a => Append; open for writing at end-of-file or create for writing if the file does not exist.

a+ => Open for append; open (or create if the file does not exist) for update at the end of the file.

Merci !
