Hi all, I am extremly confused about data types in CCS. Help tells me the following: Type Size Representation char, unsigned char 16 bits ASCII short, signed short 16 bits 2s complement unsigned short 16 bits Binary int, signed int 16 bits 2s complement unsigned int 16 bits Binary long, signed long 32 bits 2s complement unsigned long 32 bits Binary long long 40 bits 2s complement But when checking the actual data size with 'sizeof' function I get the following: sizeof(char) = 1 sizeof(long) = 2 sizeof(long long) = 4 sizeof(int) = 1 It does not match at all. Does someone know the actual data type sizes? Thanks. |

looks like it is returning bytes? At Monday, 07 February 2005, "romaxin" <> wrote: >Hi all, > >I am extremly confused about data types in CCS.

Gee, harland its definetly not matching! Int bits and sizeof(int)= 1? Romaxin, somethhing is wrong somwhere. Can you tell us which DSP are you targeting? 54x? 55x? --Bhooshan On Tue, 08 Feb 2005 07:29:44 -0500, Harland Christofferson <> wrote: > looks like it is returning bytes? > > At Monday, 07 February 2005, "romaxin" <> wrote: > > >Hi all, > > > >I am extremly confused about data types in CCS.
