Wine API: _i64toa

NAME

_i64toa (NTDLL.@)

SYNOPSIS

 char * _i64toa
 (
  LONGLONG value,
  char*    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 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.
