_i64toa3w

Usage

Params

value [In] Value to be converted.

str [Out] Destination for the converted value.

radix [In] Number base for conversion.

Overview

Converts a large integer to a string.

Returns

str.

Notes

- Converts value to a Nul terminated string which is copied to str.

- The maximum length of the copied str is 65 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 crashes, as the native function does.

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 _i64toa function and our ntdll _i64toa function do not have this bug.
