Executing a Member Function After main() Terminates

Executing a Member Function After main() Terminates

You can execute any member function or any other execution after a termination of main() function by using “#pragma exit.”

Here’s the syntax:

 	#pragma exit  [priority] //withoutsemicolon

Now, here’s an example:

 #includeclass CL{public:	//A constructor	CL(){	cout << "
The object is creating"; }	void obj_func() { cout << "
This is a _function of object"; }};void func_after_main ();#pragma exit func_after_main 64   // setting a _function to execute afterthe main terminationvoid main (){  cout << "
This is main() ";}void func_after_main() {	cout << "
This is func_after_main() ";	CL obj1;	//creating an object, and _calling its constructor	obj1.obj_func();	//calling an _object's member function}

In defining such functions, the functions should not carry any attribute nor return any value. They should be defined before the #pragma statement.

Priority is optional. It is ranging from 64 to 100 (recomended).

  • 0?Highest priority used by C Libraries.
  • 63?Lowest priority used by C Libraries.
  • 64?First available Priority.
  • 100?Default priority.
  • 255?Lowest priority.
