wcstoimax, wcstoumax - convert a wide-character string to an integer type
Návod, kniha: POSIX Programmer's Manual
#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);
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.
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].
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.
