Hi All, Iam new to this fedora world.. a small question on the below discussion:
It is mentioned that having, zero in the third argument is legitimate use cases. Can somebody direct me to such a use case, as i feel, giving memset a zero, is asking it, not to do anything [ might have side effects, not sure from my end, though ]. Regards Roopesh M.
