SYNOPSIS
#include <util.h>
int
isduid(char *duid, int dflags);
DESCRIPTION
The isduid() function tests the string duid to see if it is a valid
disklabel(8) UID. The dflags are specified using the same flags as used
by opendev(3).
If the OPENDEV_PART flag is included in dflags the disklabel UID must
consist of a 16-character hexadecimal string. Otherwise the disklabel
UID must consist of a 16-character hexidecimal string followed by a `.'
and a partition letter.
RETURN VALUES
The isduid() function returns non-zero if duid is a valid DUID, otherwise
zero is returned.
