If there are more offset options specified, some could be lost.
Try
pvcreate /dev/sd[bcde]
mdadm -C -l 5 -n4 /dev/md0 /dev/sd[bcde]
mdadm --stop /dev/md0
wipefs -n -o 0x1000 -o 0x218 /dev/sdb
- LVM2 signature remains there
wipefs -n -o 0x218 -o 0x1010 /dev/sdb
- no report about ignored signature

Some filesystems (e.g. FAT) is possible to detect in many ways -- for
example if a magic string is stored on more places on the device. The
current implementation always removes from the device only the firstly
detected possibility.
# wipefs /dev/sdb1
offset type
----------------------------------------------------------------
0x36 vfat [filesystem]
UUID: D203-A7F4
# wipefs -a /dev/sdb1
8 bytes [46 41 54 31 36 20 20 20] erased at offset 0x36 (vfat)
# wipefs /dev/sdb1
offset type
----------------------------------------------------------------
0x0 vfat [filesystem]
UUID: D203-A7F4
This patch fixes this issue:
# wipefs -a /dev/sdb1
8 bytes were erased at offset 0x00000036 (vfat): 46 41 54 31 36 20 20 20
1 bytes were erased at offset 0x00000000 (vfat): eb
2 bytes were erased at offset 0x000001fe (vfat): 55 aa

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

Currently wipefs process only first device argument and silently ignores
remaining. Print error instead because it can be quite confusing.

This patch replaces a few functions used throughout the source:
* Renames getnum (from schedutils) to strtol_or_err
* Moves strtosize (from lib/strtosize.c)
* Moves xstrncpy (from include/xstrncpy.h)
* Adds strnlen, strnchr and strndup if not available (remove it from libmount utils)
A few Makefile.am files were modified to compile accordingly along with trivial renaming
in schedutils source code.
