What version of FreeBSD are you using. On a 4-day-old 4.0-CURRENT,
fstat(2) seems to fill st_bklsize correctly. The following sample code
prints 8192 for every file I tested on my system.
Ciao,
Sheldon.
#include <sys/types.h>
#include <sys/stat.h>
#include <err.h>
#include <fcntl.h>
#include <stdio.h>
int
main(int argc, char *argv[])
{
struct stat t;
int fd;
if (argc != 2) {
(void)fprintf(stderr, "a single path argument is required\n");
return 1;
}
if ((fd = open(argv[0], O_RDONLY)) == -1)
err(1, NULL);
if (fstat(fd, &t) == -1)
err(1, NULL);
printf("%d\n", t.st_blksize);
return 0;
}
