Check for the MNT_LOCAL flag in f_flags.
For example:
#include <sys/param.h>
#include <sys/ucred.h>
#include <sys/mount.h>
#include <stdio.h>
int
main() {
struct statfs *fs, *fsa;
int cnt;
cnt = getmntinfo(&fsa, 0);
if (!cnt) {
fprintf(stderr, "getmntinfo() failed\n");
exit(1);
}
for (fs = fsa; cnt != 0; fs++, cnt--)
printf("%s %d\n", fs->f_fstypename, (fs->f_flags & MNT_LOCAL) == MNT_LOCAL);
exit(0);
}
Hope that helps.
