20 These functions shall be equivalent to the wcstol(), wcstoll(),
21 wcstoul(), and wcstoull() functions, respectively, except that the ini‐
22 tial portion of the wide string shall be converted to intmax_t and
23 uintmax_t representation, respectively.
24
26 These functions shall return the converted value, if any.
27
28 If no conversion could be performed, zero shall be returned. If the
29 correct value is outside the range of representable values, {INT‐
30 MAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be returned (according
31 to the return type and sign of the value, if any), and errno shall be
32 set to [ERANGE].
33
35 These functions shall fail if:
36
37 EINVAL The value of base is not supported.
38
39 ERANGE The value to be returned is not representable.

42 These functions may fail if:
