strfree (
    char **string)

Synopsis

Releases memory occupied by a string. Call this function only when you previously allocated the string using malloc or strdupl(). You pass the address of a char pointer; this function sets the pointer to NULL. This is a safety measure meant to make it safe to try to free non-allocated strings. In your code, initialise all such pointers to NULL. Returns the address of the modified pointer.

    return (string);
}
