The “big stack model” assumes that a compiled program will allocate “stack frames” for function calls in a contiguous region of memory, using machine instructions … Read more
Normally you would set the stack size early on, e,g, at the start of main(), before calling any other functions. Typically the logic would be: call getrlimit to get current stack size if current size < required stack size then call setrlimit to increase stack size to required size In C that might be coded … Read more
