Re: Re: finding inplace alters

Here's a little test program based on how I do it in my ul.ec utility: #if !defined LITTLE_ENDIAN # define LITTLE_ENDIAN 1234 #endif int EndianNess; int DetermineEndianNess() { int testint = 0x04030201, ii, result = 0, mult=1000; char *p = (char *)&testint; for ( ii=0; ii < 4; ii++) { result += mult * p[ii]; mult /= 10; } return result; } int main() { EndianNess = DetermineEndianNess(); printf( "LITTLE_ENDIAN=%d. EndianNess = %d.\\n", LITTLE_ENDIAN, EndianNess ); if (EndianNess == LITTLE_ENDIAN) { printf( "LITTLE_ENDIAN\\n" ); } else /* BIG_ENDIAN */ { printf("BIG_ENDIAN\\n" ); } return 0; } Art S.
