[En-Nut-Discussion] pointer don't work?

[Landsperger, Werner]

Hey Stefan,

sorry I don't understand you completely. This Codesniped is only a
sample and not the whole code. The buff I'm reading in contents 128
bytes/chars. But the pointer doesn't work and I dont know why. Do you
know what I mean?

Greets,

Werner

fread() returns a char count but the buffer handed to fread does not get
null terminated ... you have to look at cnt.
