#define today april_1st

I like the way the C language has been evolving: as machine word
will be getting bigger and bigger, someday our descendens would
be using long long long long type to work 128 bit integers. The
road is bright, straight and infinite!

Apparently, MS has chosen a different, and more effective mean to
extend data types, namely double underscore prefix and bit count
suffix, so their extended 64 bit type is __ then int then 64.
It is clear that a 128 bit integer type is an extension of the
extended type and it would be denoted as ____int128.

I hope my demise would happen before this "brave new world" :)

P.S. One more obsevation: as the order of keywords does matter,
e.g. int unsigned is invalid, you can type long long, but cannot
long long. Prove me wrong! :)))

Also, keeping in mind that long is a shorthand for signed long int,
try to imagine what unsigned long long might mean :)

The standard defines the MINIMUM sizes for types. A C compiler
implementation is free to make a type larger than specified in the standard
(and therefore have different values than the defaults for the xxx_MAX
constants). 

Quote from the document referenced below regarding xxx_MAX constants.
"Their
implementation-defined values shall be equal or greater in magnitude
(absolute value) to those shown, with the same sign."

Therefore the minimum size of an unsigned long long as defined by the
standard is 64 bits. It could be larger depending on implementation. On C6x
it is 64bits.

Also, I happen to use the unsigned long long type for a time value
from an NTP server which uses a 64-bit number to represent time and it
works fine on a DM642 with CCS 3.1.

From the combined C99 + TC1 + TC2 standard at
http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1124.pdf the long
long types maximum value constant, ULLONG_MAX, is defined to be 2 ^ 64
- 1 which implies that the type must hold at least 64 bits of
information.

Also, I happen to use the unsigned long long type for a time value
from an NTP server which uses a 64-bit number to represent time and it
works fine on a DM642 with CCS 3.1.

My understanding is that:

40- bit long is NOT consisten with any other compiler, let alone being ANSI-C compliant; In fact I dont think ANSI is in the habbit of defining data type size beyond 32 bit. Am I wrong here?

The correct data type is as follows:

40-bit: long

This is consistent with Ansi-C.

hi,
as far as i remember, long will take 40 bit in C6x.
so, i doubt long long will be equivalent to 64bit.
instead double should serve the purpose.
please correct me guys if i understood wrongly.

The correct data type is as follows:

64 bit integers; long long and unsigned long long

64 bit floating point; double.

40-bit: long

This is consistent with Ansi-C.
