> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Affects Versions: proton-c-0.22.0
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Minor
> Fix For: proton-c-0.23.0

>
> Encapsulates the awkward allocate-encode-expand dance required by
> pn_message_encode()
> Supports the following 2 scenarios:
> 1. Simple: don't care about allocations, just send `pn_message_t *msg` and
> forget it:
> pn_message_send(msg, sender, NULL)
> 2. Efficient: re-use a buffer, buffer is allocated and expanded as required:
> pn_rwbytes_t buffer=\{0}; // Zero initialize, libary will do the
> allocation
> ...
> pn_message_send(msg, sender, &buffer); // Expand as needed
> pn_message_send(msg2, sender2, &buffer); // etc.
> ...
> free(buffer->start); // Application must do final free of buffer
