Thread: How can I set a file pointer to zero? Casting?

I want to initialize my FILE* fp (file pointer) to zero. Which is a data member of my class.

17 invalid conversion from `int' to `FILE*'

in my header

const void setFileP(int m){ fp = m; } //Sets FP to an integer


and in my class

Code:

void Bank::init(int n, int m)
{
     setSize(n);
     setFileP(m);
}
