PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
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 ini-
       tial  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, {INT-
       MAX_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.
