WCSTOIMAX

Updated: 2003
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.
