NAME
       wcstoimax, wcstoumax - convert a wide-character string to an integer type


SYNOPSIS
       #include <stddef.h>
       #include <inttypes.h>

       intmax_t wcstoimax(const wchar_t *restrict nptr,
              wchar_t **restrict endptr, int base);
       uintmax_t wcstoumax(const wchar_t *restrict nptr,
              wchar_t **restrict endptr, int base);


DESCRIPTION
       These  functions  shall  be  equivalent  to the wcstol(), wcstoll(), wcstoul(), and wcstoull() functions,
       respectively, except that the initial portion of the wide string  shall  be  converted  to  intmax_t  and
       uintmax_t representation, respectively.


RETURN VALUE
       These functions shall return the converted value, if any.

       If no conversion could be performed, zero shall be returned. If the correct value is outside the range of
       representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be returned  (according  to  the
       return type and sign of the value, if any), and errno shall be set to [ERANGE].


ERRORS
       These functions shall fail if:

       EINVAL The value of base is not supported.

       ERANGE The value to be returned is not representable.

       These functions may fail if:

       EINVAL No conversion could be performed.
