Assigning Content of a Variable to a Pointer Not Working in C and proC

Question

I am having the following problem in my C code on a UNIX Platform.

 function1(short *a)
 {
    EXEC SQL begin declare section;
          short a1;
    EXEC SQL end declare section;

    EXEC SQL fetch quey_cursor
     into
          :a1;

    // More processing

    *a = a1;

 }

The problem is the program is exiting at this line

  *a = a1;

and I am not able to get debugs.

I really appreciate any help

Thanks

Answer 1

You have to pass to function1() a valid pointer to a short for the assignment to *a to work. The error is in where function1() was called.

Answer 2

From your comment, you are not allocating memory for the pointer. So, when you try to dereference it as *a=a1 , it's crashing. Since, it's only a single pointer, you can simply declare and use it as:

function() { 
   short a; 
   function1(&a);
}

Notice the difference with declaration and argument passed.
