PROLOG

NAME

13       wcstoimax, wcstoumax — convert a wide-character string  to  an  integer
14       type
15

SYNOPSIS

17       #include <stddef.h>
18       #include <inttypes.h>
19
20       intmax_t wcstoimax(const wchar_t *restrict nptr,
21           wchar_t **restrict endptr, int base);
22       uintmax_t wcstoumax(const wchar_t *restrict nptr,
23           wchar_t **restrict endptr, int base);
24

DESCRIPTION

26       The  functionality described on this reference page is aligned with the
27       ISO C standard. Any conflict between the  requirements  described  here
28       and  the  ISO C  standard is unintentional. This volume of POSIX.1‐2008
29       defers to the ISO C standard.
30
31       These  functions  shall  be  equivalent  to  the  wcstol(),  wcstoll(),
32       wcstoul(), and wcstoull() functions, respectively, except that the ini‐
33       tial portion of the wide string shall  be  converted  to  intmax_t  and
34       uintmax_t representation, respectively.
35

RETURN VALUE

37       These functions shall return the converted value, if any.
38
39       If  no  conversion  could  be performed, zero shall be returned. If the
40       correct value is outside  the  range  of  representable  values,  {INT‐
41       MAX_MAX},  {INTMAX_MIN},  or {UINTMAX_MAX} shall be returned (according
42       to the return type and sign of the value, if any), and errno  shall  be
43       set to [ERANGE].
44

ERRORS

46       These functions shall fail if:
47
48       EINVAL The value of base is not supported.
49
50       ERANGE The value to be returned is not representable.
51
52       These functions may fail if:
53
54       EINVAL No conversion could be performed.
