psmq is tool set which allows IPC communication in publish/subscribe way
|
||
created on top of posix messege queue. Full documentation is available
|
||
at: https://psmq.kurwinet.pl (despite the domain, it is in english).

config PSMQ_MAX_CLIENTS
|

int "Max number of clients"
|

default 8
|
||
---help---
|
||
This defines how many clients single broker process will
|
||
support. Broker will return error for clients that want to
|
||
register to it and there are already max clients connected. psmqd
|
||
will alocate client array with static storage duration that is
|
||
about 12 bytes (may vary depending on architecture) for each
|
||
client.
|
||
|
||
config PSMQ_PAYLOAD_MAX
|
||
int "Max size of payload"
|
||
default 8
|
||
---help---
|
||
Defines maximum size of payload that can be sent via psmq.
|
||
|
||
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.
|
||
|
||
config PSMQ_TOPIC_MAX
|
||
int "Max length of topic"
|
||
default 15
|
||
---help---
|
||
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.
