__wrap_atexit()

int __wrap_atexit

(

void(*

)(void)

)

Wrapper for atexit, returns 0 without registering anything.

On normal systems, atexit registers a function to be called on exit. Embedded systems do not use exit(), so it is safe to skip. Saves flash by eliminating destructor registration.

Linker flag:

-Wl,--wrap=atexit
