Hi Bryan
But the returned uintptr from syscall is as far as i know a pointer to a
struct which has been created by the C API, so go runtime won't touch it or
do I miss something?

Jesse,
what you quoted is an optimisation for the "Otherwise, the value passed is
a new slice of type []T with a new underlying array whose successive
elements ".
Your quote says: if the final argument is assignable - it may be passed as
is, without any copy involving.

In this case, the vet tool is correct if you're making the syscall with
Go-allocated memory.
The Go runtime is allowed to move values around: the address of a Go
variable is only pinned for the duration of the syscall itself.
If you've got C-allocated memory (or statically-allocated
memory), ht

It depends a lot on what your application does, but I’d try the trace tool,
which should give you execution times of your request and you see its
interactions with the garbage collector. For reasonable allocation rates you
may find that the gc can collect in the background and not introduce add

AddressList doesn't seem to like it when the email name is encoded in RFC

IMHO //go:generate ... tasks inside a file marked by // +build ignore
should run. Any file that is marked by // +build ignore will be ignored by
the compiler. So your code (by putting // +build ignore inside main.go)
will generate a compilation error.

Okay I found a way, this seems to work:
ca := (*[100]byte) (unsafe.Pointer(certctx.pbCertEncoded))[:certctx.
cbCertEncoded]
or
mm := make([]byte, certctx.cbCertEncoded)
for i := uint32(0) ; i < certctx.cbCertEncoded; i++ {
mm[i] = *((*byte)(unsafe.Pointer(certctx.pbCertEncoded +

I'm using syscall package and no C import, but maybe it is possible to use

Are you talking about https://pythonhosted.org/Pyro4/ ?
It really depends on the serialization format used. If it's json, msgpack
or any other language independent format that you can do it. If it's Python
specific (marshal, pickle, ...) then you can probably invoke some python
code to convert
Do you mean
func C.GoBytes(unsafe.Pointer, C.int) []byte
?
