21 These functions are equivalent to the wcstol(3C), wcstoll(3C),
22 wcstoul(3C), and wcstoull(3C) functions, respectively, except that the
23 initial portion of the wide string is converted to intmax_t and uint‐
24 max_t representation, respectively.
25
27 These functions return the converted value, if any. If no conversion
28 could be performed, 0 is returned. If the correct value is outside the
29 range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINT‐
30 MAX_MAX} is returned (according to the return type and sign of the
31 value), and errno is set to ERANGE.
32
34 These functions will fail if:
35
36 EINVAL The value of base is not supported.
37
38
39 ERANGE The value to be returned is not representable.

43 These functions may fail if:
