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.
