Wine API: _i64tow

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 '\0' 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.
