Prototype

Code Block
void  OSRedzoneHitHook (OS_TCB  *p_tcb)

Arguments

p_tcb

is a pointer to the TCB of the offending task. Note that p_tcb can be NULL. In that case, the ISR stack is corrupted.

...

In the example below, OSRedzoneHitHook() calls App_OS_RedzoneHitHook() if the pointer OS_AppRedzoneHitHookPtr is set to that function.
