tcpip_try_callback() function

Call a specific function in the thread context of tcpip_thread for easy access synchronization. A function called in that way may access lwIP core code without fearing concurrent access. Does NOT block when the request cannot be posted because the tcpip_mbox is full, but returns ERR_MEM instead. Can be called from interrupt context. @see tcpip_callback

Syntax

err_t tcpip_try_callback(tcpip_callback_fn function,     void *ctx);
Implemented in tcpip.c:344

Arguments

function

the function to call

ctx

parameter passed to f

Return value

ERR_OK if the function was called, another err_t if not
