NAME¶

_i64tow (NTDLL.@)

SYNOPSIS¶

LPWSTR _i64tow
(
LONGLONG value,
LPWSTR str,
INT radix
)

PARAMS¶

value [In] Value to be converted. str [Out] Destination for the converted value. radix [In] Number base for conversion.

DESCRIPTION¶

Converts a large integer to a unicode string.

RETURNS¶

Always returns str.

NOTES¶

Converts value to a ' ' terminated wstring which is copied to str. The maximum length of the copied str is 33 bytes. If radix is 10 and value is negative, the value is converted with sign. Does not check if radix is in the range of 2 to 36. If str is NULL it just returns NULL.

DIFFERENCES¶

- The native dll converts negative values (for base 10) wrong: -1 is converted to -18446744073709551615 -2 is converted to -18446744073709551614 -9223372036854775807 is converted to -9223372036854775809 -9223372036854775808 is converted to -9223372036854775808 The native msvcrt _i64tow function and our ntdll function do not have this bug.

IMPLEMENTATION¶

Declared in "msvcrt/stdlib.h". Implemented in "dlls/ntdll/wcstring.c".
