Casting a function pointer to a void* is not a portable operation.

Who says he cares about portability? It's quite obvious from what
he's doing that he has very system-specific goals.

And if he did care about portability, who says he cares about ISO C
portability as opposed to POSIX portability? Making the cast under
POSIX is perfectly acceptable.

No one has had any authority to impose an ANSI/ISO C topicality
restriction on this newsgroup. Some of us are going by the founding
message. You can't stop us giving people the help they seek.

The OP (not nicolas), in his other thread about environment
variables, was told to post to comp.unix.programmer, where people
from this newsgroup simply whined about his spelling and English
and offered no substantial help whatsoever or showed any indication
that they knew what he was doing. Answer: he's working with security
programming and wanted to transfer execution to machine code
stored in the environment. I don't know why, after his other posts,
people drew the bizarre conclusion that he was wanting some kind of
efficient access to the environment.

Yours,
Han from China

Did I ask him not to post here? Did I ask him to post elsewhere? So
you have decided that informing someone that something is not portable
in ANSI C is not only undesirable but is also equivalent to imposing a
topicality restriction.

I am not allowed to tell him it is not portable but you are allowed to
tell me I cannot tell him? Interesting hypocrisy.

Bear in mind that 'Anonymous' is a pure troll.
