I am working on porting lwIP into RTX-RTOS. In lwIP's "sys_arch.c" file, I need to implement functions to free up semaphores, mutexes and mailboxes. RTX-RTOS does not have any functions for this.
Since a mailbox is a pointer to a block of memory, can "_free_box" be used to free a mailbox?
How about for a semaphore or a mutex?
Thanks,
Willy
or any architecture supported by Keil?
