Problem:

A common pattern is:

GUARD(s2n_stuffer_skip_write(stuffer, bytes_to_write));
uint8_t* ptr = suffer->blob.data + stuffer->write_cursor - bytes_to_write;

which could be simplified.

Solution:

*ptr could be an *out parameter to s2n_stuffer_skip_write

• Does this change what S2N sends over the wire? No.
• Does this change any public APIs? No.

It would be a cool proof of concept to see Flecs running in the browser. As a first step towards this, the ecs_graphics project could be ported as it showcases the bare minimum for a game with graphics (input + rendering).

Introduce a decode flag that produces a vertically flipped image, this would only be valid in non-progressive mode.

pDescription may be null and causes a hard-fault when observers are notified of a resource update.

It's set to NULL when an null or empty string is passed in as a resource description on CoAP_CreateResource:

For readability and maintenance the new BLS implementation can be made in Lua script with a very small computational overhead in Zenroom.
