How to define this in slice?
Supposing I have a C function
int ReadFile(int hFile, byte* pBuffer, int nBufLen);
How to define the pBuffer in slice? is sequence<byte> the only way? if so, the nBufLen is no necessary, right?
Thanks.
int ReadFile(int hFile, byte* pBuffer, int nBufLen);

Yes, that is correct.

Is it possible to define the ReadFile in Slice as
int ReadFile(int hFile, byte* pBuffer, int nBufLen); ??

The slice compiler seems does not support
int ReadFile(int hFile, byte* pBuffer, int nBufLen);
If I want to transfer large amount of data, sequence is the only way??0 -

Yes. Passing a pointer to a buffer doesn't make sense because the buffer is in the sender's address space and pointer value would not make sense in the receiver's address space. In other words, what you must transfer is the data itself, not just a pointer to the data. Transmitting a sequence of bytes does exactly that.
