Summary: [c] make it easier to send a message
Key: PROTON-1823
URL: https://issues.apache.org/jira/browse/PROTON-1823
Project: Qpid Proton
Issue Type: Improvement
Components: proton-c
Affects Versions: proton-c-0.22.0
Reporter: Alan Conway
Assignee: Alan Conway
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
