corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
wcstoimax, wcstoumax — convert a wide-character string to an
integer type
Синопсис (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);
Описание (Description)
The functionality described on this reference page is aligned
with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This
volume of POSIX.1‐2017 defers to the ISO C standard.
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.
Возвращаемое значение (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].
Ошибки (Error)
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.
