The function savevar() saves the values and names of variables to the file system.

It returns a 0 for a successful operation, and nonzero otherwise

int savevar ( all address );

Example:

void main()

{

    int x = 0;

    loadvar(x);

    if(x == 0)

    {

      printf("Variable x not saved");

      x = 4711;

      savevar(x);

    }

    loadvar(x);

    printf("Variable x : %d",x);

    clearvar();

}

Output:

  Variable x not saved

  Variable x : 4711
