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

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 IEEE Std 1003.1-2001 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.

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.
