Both PSMQ_TOPIC_MAX and PSMQ_PAYLOAD_MAX have direct impact on size
|
|
|
|
|
|
of internal message structures that are copied each time message
|
|
|
|
|
|
is sent. If you set PSMQ_PAYLOAD_MAX to, let's say 20, and you are
|
|
|
|
|
|
sending message with payload that takes only 2 byte, then 20 bytes
|
|
|
|
|
|
will get copied anyway. Same rule applies to topics.

Defines maximum length any topic can be. That includes first ´/´
|
|
|
|
|
|
character, but does not include terminating null character. So
|
|
|
|
|
|
if this is set to 3, then topics "/0", "/01" will be valid, but
|
|
|
|
|
|
"/012" will be too long.

Library will use PSMQ_TOPIC_MAX + 1 as an array size for topic.

This means, to prevent unecessary paddings, use values like 7, or 15
|
|
|
|
|
|
or 31.
