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.bofc.pl (despite the domain, it is in english).

int "Max number of clients"

|
|
---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 allocate client array with static storage duration that is
|
|
about 12 bytes (may vary depending on architecture) for each
|
|
client.

config PSMQ_MSG_MAX

int "Max size of payload"

range 6 2147483647
|

default 24
|
|
---help---
|
|
Defines maximum size of message that can be sent via psmq.
|
|
Message consists of topic and payload. Topic is always
|
|
null-terminated after which payload follows. This allows
|
|
for some flexibility, ie if PSMQ_MSG_MAX was be 10, then
|
|
topic could be 3 bytes long and payload 7, but also
|
|
topic could take 9 bytes and payload only 1.
|
|
|
|
This value has direct impact on runtime memory usage by
|
|
psmq as this increases size of struct that is used when
|
|
allocating memory for client. This has no impact on
|
|
number of bytes that are sent because only actual data
|
|
is sent over mqueue.
