WCSTOIMAX(3P)                                       POSIX Programmer's Manual                                      WCSTOIMAX(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult 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 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.
