Hi,
i've got a c declaration that i like to wrap:
void crypto_ed25519_sign(u8 signature[64],
const u8 secret_key[32],
const u8 *message,
size_t message_size)
c2nim produces this:
proc crypto_ed25519_sign*(signature: array[64, uint8]
secret_key: array[32, uint8] message: ptr
uint8
message_size: csize)
to actually use it i had to change it like this:
proc crypto_ed25519_sign*(signature: array[64, uint8];
secret_key: array[32, uint8]; message: ptr
openarray[uint8];
message_size: csize) {.cdecl, importc:
"crypto_ed25519_sign".}
the questions are:
* what is the correct way to give arbitrary length data to message?
(so what ist the eqvivalent to const u8 *message)
* Atm i work around my limitation by declareing
message: array[1024, uint8]
and give the actual msg size in message_size.
It seems system.nim declares a dummy 10_000 size array to avoid bound checks so
i guess this is a somewhat convenient way of doing it?
greetings
