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.
