Ok, neue Variante mit statvfs().

Thx. Habe noch den hoffentlich letzten Bug
in der Struktur gefixt
Ich muss mir definitiv noch eine x64 VM
einrichten, so sind meine Codes per Default
falsch...

Na ich hoffe, dass der Code nun seinen
Zweck erfüllt!
zumindest auf UTF-8 Systemen *hust*

na, ob die ursprünglich umständliche Zerlegung des
df-Rückgabestrings doch nicht einfacher gewesen wäre?

Grüße ... Kiffi

[remi_meier]

Nächstes mal krieg ich das doppelt so
schnell und doppelt so richtig hin!
Und dann finde ich auch noch die
richtige GCC Option, die mir für 64bit
die Header preprocessed...
