Hi,

i want to know if mq_send is protected from multi source call?

do i need to protect mq_send with mutex?

HI Asaf,

mq_send is reentrant, but if you are using the same message i don't think there is protection around the passed parameters.

Hi,

You suggest to set mutex around mq_ send?

If a variable is being used by two functions, and you can't guarantee that one won't interrupt the other during an operation, then yes. I believe this is the case for mq_send().
