WebOct 30, 2011 · 3. The function does indeed work. As the documentation states: Each function returns the __int64 value produced by interpreting the input characters as a number. The return value is 0 for _atoi64 if the input cannot be converted to a value of that type. So you have to make sure that a correct string is passed.
