FUNCTION
<<itoa>>---integer to string
INDEX
itoa
ANSI_SYNOPSIS
#include <stdlib.h>
char *itoa(int <[value]>, char *<[str]>, int <[base]>);
char *__itoa(int <[value]>, char *<[str]>, int <[base]>);
DESCRIPTION
<<itoa>> converts the integer [<value>] to a null-terminated string
using the specified base, which must be between 2 and 36, inclusive.
If <[base]> is 10, <[value]> is treated as signed and the string will be
prefixed with '-' if negative. For all other bases, <[value]> is treated as
unsigned. <[str]> should be an array long enough to contain the converted
value, which in the worst case is sizeof(int)*8+1 bytes.
RETURNS
A pointer to the string, <[str]>, or NULL if <[base]> is invalid.
PORTABILITY
<<itoa>> is non-ANSI.
No supporting OS subroutine calls are required.
