QCBOREncode_Init buffer

[janemba]

Hi,

This is not an issue but I don't know where I can ask question about the API.

So I am trying to use qcbor using a simple structure but it's difficult to understand how the API works just by reading the source. I'm stuck in the beginning with the second parameter of QCBOREncode_Init function.

This parameter is supposed to be the buffer after encoding. Looking at example.c and test/qcbor_encode_tests.c the size of the buffer doesn't seem to be calculated. For one case, the declaration is static uint8_t spBigBuf[2200] and for the other case MakeUsefulBufOnStack( EngineBuffer, 300).

Is there a way to give the real size for the buffer ?

I have another question. In which case should I use MakeUsefulBufOnStack or UsefulBuf_FROM_BYTE_ARRAY ?

See if the improved documentation and sample code from #65 helps this for you.

Appreciate the comment!
