|
|
* 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.

|
|
* 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
|
