The first arg to statvfs is a directory or file, not a device.

gcc should complain about %d They should be %ld
This works for me:
==========================================================
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/statvfs.h>
char *mt[] = { "/", "/home", "/opt", "/usr", "/usr/OV", "/usr/src",
"/usr/src/gnu", "/usr/src/misc", "/var", "/var/cdtemp", "/vmdisks",
"/tmp", "/old", "/d", "/c", "/e", NULL
};
int main(int argc, char *argv[])
{
int n;
struct statvfs vfs;
for (n = 0; mt[n]; n++) {
if (statvfs(mt[n], &vfs) == -1)
printf("partition lookup failed%s\n", mt[n]);
else {
printf("size = %5ld, blocks = %7ld free = %7ld %s\n",
vfs.f_frsize, vfs.f_blocks, vfs.f_bfree, mt[n]);
} /*end if */
} /* end for */
return 0;
} /* end vfs.c */
==========================================================
