Tool/software: TI-RTOS
I have pointers to data structure with a size of 2kB and I want to pass them between threads frequently. Writing is quite obvious. However reading seems to be not very clear since reading function has the following definition Osi_MsgQRead(OsiMsgQ_t *queue, void* pMsg, OsiTime_t timeout). As I can see the second parameter is just a pointer to void which ensures me that data from the written pointer is copied into the passed pointer. Therefore a natural question arises: why not to accept void **ptr and just save the written pointer in order to avoid making copies of data? Moreover it is embedded system where too much of copying can lead to a poor performance.
What about the issue, the only solution I can see now is to create a wrapper for my message pointer in the following way and pass it to the queue:
struct wrapper {
MyMsg *msg;
}
Is there any better approach?
