- Defines: longlong2str();
-
- longlong2str(dst, radix, val)
- converts the (longlong) integer "val" to character form and moves it to
- the destination string "dst" followed by a terminating NUL. The
- result is normally a pointer to this NUL character, but if the radix
- is dud the result will be NullS and nothing will be changed.
-
- If radix is -2..-36, val is taken to be SIGNED.
- If radix is 2.. 36, val is taken to be UNSIGNED.
- That is, val is signed if and only if radix is. You will normally
- use radix -10 only through itoa and ltoa, for radix 2, 8, or 16
- unsigned is what you generally want.
-
- _dig_vec is public just in case someone has a use for it.
- The definitions of itoa and ltoa are actually macros in m_string.h,
- but this is where the code is.
-
- Note: The standard itoa() returns a pointer to the argument, when int2str
- returns the pointer to the end-null.
- itoa assumes that 10 -base numbers are allways signed and other arn't.
