[Mono-list] Managed equivalent of memset?

[Antonello Provenzano]

Frederik,

Managed code is by definition "managed", that means the memory is
handled by the VirtualMachine: so you can't operate on the memory
directly.
You should try to look for an "unsafe" (if you don't know what
'unsafe' means in such context, read the manual...) solution, that
could be found around somewhere by googling a bit.

Cheers
