wcstoimax, wcstoumax - convert wide-character string to integer type
#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 are equivalent to the wcstol(3C), wcstoll(3C), wcstoul(3C), and wcstoull(3C) functions, respectively, except that the ini- tial portion of the wide string is converted to intmax_t and uintmax_t representation, respectively.
These functions return the converted value, if any. If no conversion could be performed, 0 is returned. If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} is returned (according to the return type and sign of the value), and errno is set to ERANGE.
These functions will 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.
