NAME

_itoa(NTDLL.@)

SYNOPSIS

 char * _itoa
 (
  int   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 an integer to a string.

RETURNS

str.

NOTES

- Converts value to a '\0' terminated string 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 crashes, as the native function does.
