Synopsis:
    #include <stdlib.h>
    char *utoa( unsigned int value,
                char *buffer,
                int radix );
    char *_utoa( unsigned int value,
                 char *buffer,
                 int radix );
    wchar_t *_utow( unsigned int value,
                    wchar_t *buffer,
                    int radix );
    wchar_t *_utou( unsigned int value,
                    wchar_t *buffer,
                    int radix );

Description:
    The utoa function converts the unsigned binary integer value into the
    equivalent string in base radix notation storing the result in the
    character array pointed to by buffer.  A null character is appended to
    the result.  The size of buffer must be at least (8 * sizeof(int) + 1)
    bytes when converting values in base 2.  That makes the size 17 bytes on
    16-bit machines, and 33 bytes on 32-bit machines.  The value of radix
    must satisfy the condition:


         2 <= radix <= 36

    The _utoa function is identical to utoa.  Use _utoa for ANSI/ISO naming
    conventions.

    The _utow function is identical to utoa except that it produces a
    wide-character string (which is twice as long).

    The _utow Unicode function is identical to utoa except that it produces
    a Unicode character string (which is twice as long).

Returns:
    The utoa function returns the pointer to the result.

Example:
    #include <stdio.h>
    #include <stdlib.h>

    void main()
      {
        int base;
        char buffer[18];

        for( base = 2; base <= 16; base = base + 2 )
          printf( "%2d %s\n", base,
                  utoa( (unsigned) 12765, buffer, base ) );
      }

    produces the following:

     2 11000111011101
     4 3013131
     6 135033
     8 30735
    10 12765
    12 7479
    14 491b
    16 31dd
