// - Ignore leading and trailing whitespace

// - If the string starts with '0', parse as octal
//
// - If the string starts with "0x" or "0X", parse as hexadecimal
//
// - Otherwise, parse as decimal
//
// - return value == true indicates a successful conversion and result contains the converted value
//
// - if pos == string::npos, there are no trailing non-whitespace characters following the converted string
//
// - if pos != string::npos, there are trailing non-whitespace characters following the converted string;
// pos indicates the first such character
//
// - return value == false indicates an unsuccessful conversion:
//
// - result == 0 indicates that no digits were available for conversion
//
// - result == INT64MIN or result == INT64MAX indicate underflow or overflow.
//
// - if pos == string::npos, the string did not contain trailing non-whitespace characters
//
// - if pos != string::npos, the string contained trailing non-whitespace characters following the
// digits and pos indicates the first such character. (Note that all digits up to the first
// non-digit, non-whitespace character are consumed, regardless of how far into the digit string
// an overflow is detected.)
