The quick_exit() function is defined in the stdlib header file. The quick_exit() function is used for normal termination of a process without completely cleaning the resources.
- If val is zero or EXIT_SUCCESS, it shows successful termination of program.
- If the value is non-zero or EXIT_FAILURE, it shows that the program is not successfully terminated. These functions are called in the reverse order of their calling.
Syntax:
void quick_exit(int val);
Parameter: This method takes a single parameter val which is an integral value that represent the exit status of a program. Return Value: This function doesn’t returns anything.
Time Complexity: O(1)
Auxiliary Space: O(1)
Below program illustrate the quick_exit() function in C++:
Example:-
cpp
// c++ program to demonstrate // example of quick_exit() function. #include <bits/stdc++.h> using namespace std;
void function1()
{ cout << "Exit Function 1" << endl;
} void function2()
{ cout << "Exit Function 2" << endl;
} int main()
{ // registering function
at_quick_exit(function1);
at_quick_exit(function2);
quick_exit(0);
return 0;
} |
Output:
Exit Function 2 Exit Function 1
