wcstoll manual

wcstoll() - Convert wide string to a long long integer

The wcstoll() function converts the initial part of the in wide string to a long long integer value according to the given base, which must be between 2 and 36 inclusive, or be the special value 0.

Return Value

The wcstoll() function returns the result of the conversion, unless the value would underflow or overflow.
If an underflow occurs, wcstoll() returns LLONG_MIN.
If an overflow occurs, strtol() returns LLONG_MAX.
In both cases, errno is set to ERANGE.

Notes

Since 0 can legitimately be returned on both success and failure, the calling program not needed set errno to 0 before the call.
