PB_ENCODE_ARRAYS_UNPACKED

[Dietmar]

Hi,

I'm trying to encode an array in the unpacked format. It contains 192 sfixed64 elements, pb_get_encoded_size() calculates 1728 Bytes length of the encoded message.

When calling pb_encode_ex(...,PB_ENCODE_DELIMITED), there's the error message "stream full" in file pb_encode.c, line 746. This if statement checks (stream->bytes_written + size > stream->max_size). The actual values are 2 + 1728 > 1728.

I saw that this does not happen when using pb_encode() instead of pb_encode_ex().

Does anybody have an idea?

Thanks.
Best regards,
Dietmar

PB_ENCODE_DELIMITED prepends the message length to the message in varint format.
For the length 1728, encoding the length takes 2 bytes.

Hi Petteri,

your answer followed incredibly fast, thank you.

now I've a well understood base and I'll try to get my larger messages working as well.

Thanks.
