Hello, Using LwIP stack, shipped with the NXP SDK on a imxrt1062 SoM. in httpsrv_ws_api.c, the WS_send function is defined, which passes a datapointer (from the context parameter), via a message system (sys_mbox_post), to the api_queue.
I wonder how to guarantee that the pointer is still valid after sending a message via WS_send. Now, my data is placed on the stack just before calling WS_send, but since the function returns (possibly) before using the data, I'm very unsure on how to implement this. Do you have feedback on this issue? Much appreciated, Jonathan.
