The same cod= e built as an amd64 binary works with both. I don't like procstat_getfiles() anyway, and won't be using it, at almost 1 millisecond per call it's ridiculously slow, and its linked list is less us= eful and costlier to build than kinfo_getfile()'s array. Just thought it would be good to document this issue for others that run into it. cc -m32 file.c -o proctest -lprocstat #include #include #include #include #include #include #include #include #include #include int main(int argc, char **argv) { struct procstat *procstat =3D NULL; unsigned int count; struct kinfo_proc *kp =3D NULL; struct filestat_list *files =3D NULL; struct filestat *fs =3D NULL; char *ret =3D NULL; printf("starting...\n"); procstat =3D procstat_open_sysctl(); if (!procstat) { fprintf(stderr, "couldn't open procstat\n"); goto end; } printf("opened procstat\n"); kp =3D procstat_getprocs( procstat, KERN_PROC_PID, getpid(), &count ); if (!kp || count !=3D 1) { fprintf(stderr, "getprocs failed\n"); goto end; } printf("got proc, now looking up files...\n"); files =3D procstat_getfiles( procstat, kp, 0 ); if (!files) { fprintf(stderr, "getfiles failed, errno %d\n", errno); goto end; } STAILQ_FOREACH( fs, files, next ) { printf("%d -> %s\n", fs->fs_fd, fs->fs_path); } end: return 0; } --=20 You are receiving this mail because: You are the assignee for the bug.=
