What is the Atexit method?
The atexit() function registers the given function to be called at normal process termination, either via exit(3) or via return from the program's main(). Functions so registered are called in the reverse order of their registration; no arguments are passed.
How does Atexit work in C?
The atexit function is passed the address of a function func to be called when the program terminates normally. Successive calls to atexit create a register of functions that are executed in last-in, first-out (LIFO) order. The functions passed to atexit can't take parameters.
What is the difference between exit and Atexit in C?
Return Values Upon successful completion, the atexit subroutine returns a value of 0. Otherwise, a nonzero value is returned. The exit and _exit subroutines do not return a value. The unatexit() subroutine returns a value of 0 if the function referenced by Function is found and removed from the atexit list.
What is the use of Atexit module in Python?
The atexit module defines functions to register and unregister cleanup functions. Functions thus registered are automatically executed upon normal interpreter termination.
