PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

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

SYNOPSIS

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

DESCRIPTION

25       The  functionality described on this reference page is aligned with the
26       ISO C standard. Any conflict between the  requirements  described  here
27       and  the  ISO C  standard is unintentional. This volume of POSIX.1‐2017
28       defers to the ISO C standard.
29
30       These  functions  shall  be  equivalent  to  the  wcstol(),  wcstoll(),
31       wcstoul(), and wcstoull() functions, respectively, except that the ini‐
32       tial portion of the wide string shall  be  converted  to  intmax_t  and
33       uintmax_t representation, respectively.
34

RETURN VALUE

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

ERRORS

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