FUNC_UNINIT_PTR

Function pointer is uninitialized

This error is generated when a call is made through an uninitialized function pointer.

Problem

This code attempts to call a function through a pointer that has not been set.

	1:	/*
	2:	 * File: funcuptr.c
	3:	 */
	4:	main()
	5:	{
	6:		void (*a)();
	7:
	8:		a(); 
	9:		return (0);
	10:	}

2. Description of the problem and the expression that is in error.
3. Stack trace showing the function call sequence leading to the error.
4. Informational message indicating that a serious error has occurred which may cause the program to crash.

Repair

This problem normally occurs because some assignment statement has been omitted from the code. The current example can be fixed as follows

	extern void myfunc();

	main()
	{
	      void (*a)();
	      a = myfunc;
	      a();
	}
