I know, that x86 is big endian architecture
but simple programm like this:
#include <stdio.h>
#include <sys/param.h>
main () {
/* Are we little or big endian? From Harbison&Steele. */
union
{
long l;
char c[sizeof (long)];
} u;
u.l = 1;
printf ("Little endian? %s\n", (u.c[sizeof (long) - 1] == 1) ? "yes" : "no");
#if BYTE_ORDER == BIG_ENDIAN
printf("Big endian\n");
#elif BYTE_ORDER == LITTLE_ENDIAN
printf("Little endian\n");
#else
printf("Unknown\n");
#endif
}
Give me a strange result:
Little endian? no
Little endian
On my FreeBSD 4.2-BETA BYTE_ORDER = LITTLE_ENDIAN!
I`m very confused and some programms detect my machine as Little Endian, by
example freetds.
